Motogenic activity of IGD-containing synthetic peptides.
Although the IGD amino acid motif (iso-gly-asp) is a highly conserved feature of the fibronectin type I module, no biological activity has as yet been ascribed to it. We have previously reported that the gelatin-binding domain of fibronectin stimulates the migration of human skin fibroblasts into native, but not denatured, type I collagen substrata. Two IGD-containing type I modules are present...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...

متن کاملNew Cyclic Cystine Bridged Peptides from the Sponge Suberites waedoensis
Two new peptides, chujamides A (1) and B (2), were isolated from the marine sponge Suberites waedoensis, which was collected from Korean waters. Based upon the results of the combined spectroscopic analyses, the structures of these compounds were determined to be proline-riched and cyclic cystine bridged dodeca- and undecapeptides. The absolute configurations of all amino acid residues were det...
متن کاملEnzymatic N-glycosylation of synthetic Asn--X--Thr containing peptides.
The role of polyprenol sugar derivatives in the biosynthesis of certain eukaryotic glycoproteins has been partly described [ 11. Recently lipid pyrophospho-oligosaccharides, postulated as necessary intermediates to initiate N-glycosylation, were shown, when supplied to microsomes, to be effective donors to proteinic acceptors presenting at least one vacant Asn-X-zk sequence: unfolded forms of p...
