چکیده
|
A series of ile-containing elastin-derived peptide-analogs,(ile-pro-gly-val-gly)n (n=7-10) possessing remarkable and reversible coacervation property were newly synthesized. in comparison with the known elastin-derived peptideanalogs,which were so-called polypeptides,the obtained 35 to 50 mer peptides,(ipgvg)n (n=7-10) were significantly low molecular sized-polypeptides. however,they clearly exhibited coacervation property as same as the polypeptides did. because of their low molecular size,spectrographic analyses of (ipgvg)n (n=7-10) became feasible to carry out. as results of secondary structural analyses by cd and ft-ir,it was found that the coacervation property of the peptides is clearly attributed to the ordered secondary-structures,mainly,type ii β-turn. © 2013 bentham science publishers.
