The sequence Aib-Gly-Aib which corresponds to the N-terminus of the microheterogeneous peptide antibiotic trichotoxin has been studied crystallographically in the context of different protecting groups. Peptides Ac-Aib-Gly-Aib-OH (A) and Z-Aib-Gly-Aib-OH (B) form beta-turns. Both peptides show a remarkable conformational flexibility forming a large variety of beta-turns of different types.
