Abstract

The molecular Structure of N-benzyloxycarbonyl-a-aminoisobutyryl-prolyl-a-aminoisobutyryl-alanyl methyl ester (z-Aib-Pro-Aib-Ala-OMe), the amino terminal tetrapeptide of alamethicin is reported. The molecule contains two consecutive b- turns with Aib-Pro and Pro-Aib at the corners, forming an incipient 310 helix. This constitutes the first example of X2-Pro3 b-turn in the crystal structure of a small peptide.
