Abstract

Crystal structure of a terminally blocked synthetic peptide,t-Boc-L-Val-Aib-Gly-L-Leu-OMe has been investigated. Two different conformers of peptide with one co-crystallized water molecule, coexist in the crystal structure, in C2 space group. Both the conformers are stabilized by two intramolecular 1 <- 4 hydrogen bonds, between (Boc)C=O... HN (Gly) and (Val) C=O... HN (Leu), forming consecutive typeII-I' beta-turns. In the crystal, water interlinks peptide molecules,making a triangular bridge of pyramidal type.
