Crystal structure of Z-Aib-Aib-Aib-Ala-Ala-Aib-OtBu, a hexapeptide fragment of trichotoxin
Biochemical and Biophysical Research Communications, 1986The crystal structure of Z-Aib-Aib-Aib-Ala-Ala-Aib-OtBu, an end-protected hexapeptide with a sequence corresponding to residues 7-12 of several trichotoxin A-50 sequence analogues has been determined by X-ray crystallography. The hexapeptide adopts a right-handed 3(10)-helical conformation consisting of four consecutive beta-turns of type III.

The cyclic 16-membered pentadepsipeptide cyclo(Tro-Aib-Aib-Aib-Aib) (1) was crystallized from MeOH/AcOEt/CH2Cl2, and its structure was established by X-ray crystallography (Fig. 1). There are two symmetry-independent molecules with different conformations in the asymmetric unit. Two intramolecular H-bonds stabilize two beta-turns in each molecule.
