Similarly, in University of Connecticut Research & Development Corp. v. Germain 1992 ; , the court held that an agreement allowing the debtor licensee to use a patent regarding the production of certain material was an executory contract because the licensor had a continuing obligation both to refrain from granting licenses of the patent to others and not to withhold permission unreasonably for the licensee's sublicensing of the patent. Courts have also determined that a duty to pay money by one party is a material obligation sufficient to render a contract executory provided that corresponding materials obligations exist on the other side.4.

Terminal domain amino acids make to IGF-1R function in normal and malignant cells are not fully understood. Mutation at Y 950 decreases the effectiveness of the receptor, which is, however, still mitogenic in response to IGF-1. The lysine at 1003 is the ATP binding site. Mutation at the lysine 1003 results in a non-functional receptor. Mutations at the three tyrosine residues Ys ; of the tyrosine kinase domain result in an almost but not completely inactive receptor Baserga 2000 ; . Mutations of the ATP binding site that ablate kinase activity or at Y950 the major binding site for IRS1 ; abolish both proliferation and transformation Gronborg, Wulff et al. 1993; Coppola, Ferber et al. 1994; Li, Ferber et al. 1994 ; , clearly demonstrating that these residues are required for both mitogenic and transformation signaling. Autophosphorylation of the IGF-1R -subunit is unaffected by replacement of the C-terminal tyrosine residues. The total level of IGF-1R phosphorylation as well as the phosphorylation of adaptor proteins IRS1 and Shc are unaffected by the C-terminal mutated IGF-1R. Furthermore Grb-2 association with phosphorylated IRS1 and SHC was similar in cells expressing the wild type or the mutated IGF-1Rs. In conclusion, the tyrosine residues in the C-terminus of the receptor do not significantly mediate signals that use the MAP kinase or PI3-kinase pathways Esposito, Blakesley et al. 1997 ; . However, the C-terminal region of the IGF-1R is required for transformation Surmacz, Sell et al. 1995 ; . Regarding the antiapoptotic function of IGF-1R, the studies performed by O'Connor et all O'Connor, Kauffmann-Zeh et al. 1997 ; suggested that the residues important for protection against apoptosis are distinct from those involved in mitogenesis and that partially overlap with those mediating cell transformation. Thus, point mutation of some residues within C-terminal domain such as Y1250F Y1251F and H1293F K1294R ablate antiapoptotic function, whereas IGF-1R C-terminal truncation mutants d1229 and d1245 IGF-1Rs retain anti-apoptotic activity O'Connor, Kauffmann-Zeh et al. 1997 ; . Therefore, this describes an alternative antiapoptotic pathway that originates from the serines at positions 1280 to 1283, probably through the intervention of 14.3.3 protein resulting in translocation of Raf-1 to mitochondria Peruzzi, Prisco et al. 1999 ; . IGF-2 can also bind to a second receptor, IGF-2R, which is identical to the cation-independent mannose-6-phosphate receptor and serves as a scavenger receptor Moschos and Mantzoros 2002 ; Interestingly, IGF-2 can also bind to the insulin receptor subtype A IR-A ; , with an affinity similar to that of insulin. IR-A is more mitogenic than subtype B Sciacca, Costantino et al. 1999 ; , the latter having a metabolic function. IR-A is expressed in certain tumors, such as mammary cancers, and the IGF-2 IR-A interaction may play a role in cancer growth. In addition, hybrid heterodimeric receptors consisting of insulin and IGF-1 receptor subunits may form and could play a role in receptor signaling in normal and abnormal tissues. For example, one study, examining eight human breast cancer cell lines and 39 human breast cancer specimens, found that the hybrid receptor content exceeded the IGF-1R content in over 75% of the specimens. In the human breast cancer cell line MDA-MB157 these hybrid receptors were autophosphorylated in response to IGF-1. This response exceeded IGF1R autophosphorylation and led to increased proliferation, suggesting that the hybrid.

ABCA1-dependent cholesterol efflux of apoA-I is unclear. Methods and Results - We have proposed that lysine K ; residues in the YxxK motif can direct Tyr chlorination in proteins. To test this hypothesis, we engineered a series of mutations in human apoA-I. When the K residue in the YxxK motif next to Y192 was mutated to arginine, chlorination of Y192 by MPO was blocked. Y166 is resistant to chlorination and does not reside in a YxxK motif. When we introduced the YxxK motif into this region of apoA-I, Y166 was chlorinated in high yield. Importantly, we also found that methionine Met ; residues adjacent to this motif inhibit chlorination, indicating that they can act as local, protein-bound antioxidants. Met residues in apoA-I were oxidized quantitatively by MPO, and this process was completely reversed by treatment with PilB, a methionine sulfoxide reductase. Phenylalanine F ; , in contrast to Tyr, is resistant to chlorination by MPO. Remarkably, when the Y192F mutant of apoA-I was exposed to MPO and then incubated with PilB, its ability to promote cholesterol efflux by the ABCA1 pathway was almost completely restored. Conclusions - These observations strongly support the proposal that YxxK motif directs the regioselective chlorination of Tyr residues in apoA-I. They also argue against the hypothesis that the selective chlorination of Tyr192 requires MPO to interact directly with apoA-I. Our results further suggest that a combination of Y192 chlorination and Met oxidation is both necessary and sufficient for depriving apoA-I of its ABCA1-dependent cholesterol transport activity and malarone.

To be non-toxic. The ITS region of the ribosomal DNA is being amplified, sequenced and aligned to determine whether there are differences between clones that mate successfully, and those that do not. If differences are found, further investigations will follow on the potential for mating compatibility. Mating results, sequence data and discrete morphological differences may suggest the existence of semi-cryptic diversity in the P. delicatissima complex in Eastern Canadian coastal waters. 41 ACTION OF DINITROANILINE HERBICIDES IN THE PROTOZOAN PARASITE TOXOPLASMA GONDII Ayana, Marge, Bertozzi, Danelle, Heino, Aino E., Judkins, Myeika, Keogan, Shawn, Story, Elizabeth & Fichera, Maria E. Biology, Eastern University, St. Davids, PA, USA Toxoplasma parasites and relatives like Plasmodia are sensitive to dinitroaniline herbicides. It is hypothesized that dinitroanilines disrupt parasite microtubules. Our lab and others have demonstrated the effect of dinitroanilines on Toxoplasma replication -- parasites grow, replicate their DNA, but cannot split apart causing parasites to take on a blobbed appearance. Studies on herbicide resistance in goosegrass and green algae identified point mutations in -tubulin genes correlated with resistance to dinitroanilines. Through chemical mutagenesis, we have generated Toxoplasma parasite clones resistant to 1 M benfluralin or trifluralin herbicides. Parasites resistant to benfluralin exhibited a point mutation in nucleotide position 1801 of -tubulin guanine to adenine substitution ; which, when translated, revealed a substitution of valine with methionine at amino acid 252. Likewise, parasites resistant to trifluralin exhibited a point mutation in nucleotide position 1850 of -tubulin resulting in a thymine to cytosine substitution. Translation of this mutated sequence revealed a substitution of methionine with threonine at amino acid 268. These mutations are similar to known mutations that confer resistance to oryzalin another dinitroaniline ; in Toxoplasma or goosegrass. To confirm that these point mutations are responsible for the drug resistance phenotype, the mutated -tubulin gene associated with trifluralin resistance was cloned into a Toxoplasma expression vector and electroporated into wild-type parasites. Transformed parasites were subjected to drug selection using trifluralin ; , and indeed converted from wild-type to the resistant phenotype. Further studies are needed to analyze the mechanism of the insertion of the transgene. Parallel experiments will be performed using the benfluralin-associated mutation. Our studies should help to elucidate the mode of action of these dinitroaniline herbicides in Toxoplasma and their utility as inhibitors of the parasite cytoskeleton. 42 FRIENDLY IRON AND ADVERSARY ZINC MODULATE TROPHOZOITE GROWTH OF ENTAMOEBA HISTOLYTICA Espinosa, Avelina & Arnold, Shannon Biology, Roger Williams University, Bristol, RI, USA Entamoeba histolytica has cytosolic fermentation enzymes possibly acquired through horizontal gene transfer from bacteria to survive within the human intestine. This protist constitutes and ideal model to study the origin and evolution of anaerobic metabolism. Entamoeba histolytica alcohol dehydrogenase 2 EhADH2 ; is a fusion-protein with N-terminal ALDH and C-terminal ADH domains and is essential in glycolytic fermentation of E. histolytica. We have identified a member of the ADHE family from Entamoeba invadens, a reptilian and amphibian pathogen. Expression of EhADH2 and EiADHE restored the ability of a mutant E. coli strain to grow anaerobically. EiADHE showed ADH and ALDH activities with higher resistance to oxygen inactivation. Molecular and biochemical studies demonstrate these bi-functional enzymes require iron for both ADH and ALDH activities. Zinc and chelators dramatically reduced enzymatic activities and anaerobic growth of the recombinant E. coli strains transformed with pEhADH2 and pEiADHE. Addition of iron to E. colipEhADH2 and E. histolytica trophozoites significantly enhanced bacteria and amebic growth while zinc or chelators inhibited or halted it. We are currently testing metal effects on E. invadens trophozoites. These results confirm homology to bacterial alcohol dehydrogenases such as AdhII from Zimomonas mobilis, a "unifunctional" alcohol dehydrogenase. Comparisons between ADHE enzymes human, reptilian, amphibian pathogens or commensal protists will provide insights to their evolutionary history and host immune responses.
Very low intracellular arginine pool 10 to 20 times lower than usual ; when cells are grown in the presence of L-lysine. They conclude that Llysine has a negative effect on the biosynthesis of arginine, an amino acid which is required subsequently in the synthesis of protein necessary for initiation of postexponential growth. This conclusion has been contested 5, 7, 8 ; , and the suggestion has been made that the effect is far more general in scope than previously realized, since growth inhibition is observed even under conditions in which arginine is present in large amounts. Rather, it is claimed that a large pool of one basic amino acid, in this case lysine, simply displaces other basic amino acids, e.g., arginine required for postexponential growth, from the pool. Irrespective of which, if either, of these hypotheses accounts for the absence of an arginine pool, I do not believe that basic amino acid starvation adequately explains postexponential growth inhibition by lysine or any other nonutilizable nitrogen source tested. Although it does seem that protein synthesis is required 1 ; , the size and composition of the basic amino acid pool does not correlate with the presence or absence of postexponential growth on a variety of inhibitors and carbon sources used in the present study. Although D-lysine and 3-alanine were as effective inhibitors as L-lysine in the presence of glucose, the cells did contain arginine in the amino acid pools Table 1 ; . In itself this does not preclude the possibility that postexponential growth was inhibited through an absence of one or more of the other basic amino acids from the pools, since the intracellular concentration of histidine, for example, fell to an undetectable level in both cases. However, neither arginine nor histidine was detected when lactate was used as a carbon source in the presence of L-lysine, even though postexponenDownloaded from jb.asm by on March 13, 2008 and marinol.

To better understand the relationship between these two Hsp70s, we set out to analyze interactions with the ribosomeassociated nascent chains. Ssb has been crosslinked to ribosomeassociated nascent chains produced in a yeast translation extract 18 ; . However, the chains tested had a limited size distribution. To try to delineate more specifically the sites of interaction of Ssb, mRNAs were produced that encoded pCoxIV polypeptides of 152, 96, 77, or 34 amino acids Fig. 2A ; . These translated chains remained tethered to the ribosome because of the absence of a stop codon. In vitro translation was performed in the presence of [35S]methionine and lysyl-tRNAs charged with lysines bearing a photoactivatable crosslinker, TBDA. Labeled nascent chains bearing this photoactivatable probe can form covalent attachments with interacting proteins, which can be identified by immunoprecipitation. The chains of 152, 96, 77, and 54 amino acids could be crosslinked to Ssb, but we were unable to detect crosslinking to the shortest chain that was 34 amino acids Fig. 2B ; . These results are consistent with Ssb interacting with chains extending beyond the ribosome tunnel, but not those sequestered within it 30, 31 ; . The signal was significantly weaker in the 54-amino acid chain compared with the longer chains. Assuming the ribosome tunnel sequesters 40 amino acids, the only lysine expected to be exposed in this nascent chain would be the lysine at position 12, which would be very close to the exit site. To better understand the interaction of Ssb with the nascent chain, we further characterized the 96-amino acid chain. This polypeptide contains 8 lysine residues, 4 of which would be expected to extend beyond the ribosome tunnel. To assess the contribution of these 4 lysines, at positions 12, 28, 32, and 52, to the crosslinking signal, we made constructs that changed the codons encoding these lysines to those encoding arginines. As expected, if Ssb was being crosslinked to the nascent chain extending beyond the ribosome, no signal was detected if the lysines at positions 12, 28, 32, and 52 were removed. Alterations at positions 12, 28 32, or 52 gave intermediate amounts of and mechlorethamine.

Objective: Recent studies have pointed to the role of the IGF system in adrenocortical tumorigenesis. The IGF-II gene is overexpressed in malignant adrenocortical tumors and its proliferative effects are mediated by the type-1 IGF receptor IGF1R ; . The mannose 6-phosphate IGF2 receptor M6P IGF2R ; plays a key role in regulating cell growth, by ensuring the clearance and inactivation of IGF-II and facilitating activation of the growth inhibitor, transforming growth factor b TGFb1 ; . The M6P IGF2R has been implicated as a tumor suppressor gene in various human tumors. Methods: The purpose of this study was to determine if the M6P IGF2R is involved in adrenal tumorigenesis. Two polymorphisms in the 3 H untranslated region of M6P IGF2R were used to screen a large series of 76 sporadic adrenocortical tumors for loss of heterozygosity LOH ; by PCR amplification of DNA. Tumors were classified into three groups based on pathological features: benign tumors n 25Y suspect tumors n 22 and malignant tumors n 29X Results: LOH at the M6P IGF2R locus was detected in 15 of 26% ; informative tumors and was more frequent in malignant tumors 58% ; than in benign and suspect tumors 9 and 13% respectively ; . Conclusion: These findings provide evidence that LOH at the M6P IGF2R locus is a frequent event in adrenocortical tumors and support the hypothesis that it may function as a tumor suppressor gene in adrenocortical tumorigenesis.

Are electron-rich, as shown by the fact they can undergo reaction with electrophiles. It is thought that the diffuse positive charge on the NMe group is capable of distorting the pi electron cloud of aromatic rings to induce a dipole moment. Dipole interactions between the NMes group and an aromatic residue such as tyrosine would then account for the binding. A 3D model of the receptor binding site has been worked out with the aid of conformationally restrained analogues of acetylcholine. Acetylcholine itself has no conformational restraints. It is a straight-chain molecule in which bond rotation along the length of its chain can lead to numerous possible conformations or shapes ; . Thus, it is impossible to know exactly the 3D shape of the receptor site from considering acetylcholine alone. In the past, it was assumed that a flexible neurotransmitter such as acetylcholine would interact with its receptor in its most stable conformation. In the case of acetylcholine, that would be the conformation represented by the sawhorse and Newman projections shown in Fig. 11.12 and mefloquine.
