The crystal structures and molecular conformations of two tetraproline derivatives with alternating configurations Boc(D-Pro,L-Pro),OH and Boc(D-Pro,L-Pro),OCH,~ are investigated in connection with the ability of the homologous polymer to selectively increase (as an ion channel) the ion permeability

The peptide N-Boc-L-Pro-dehydro-Leu-OCH3 was synthesized by coupling dehydroleucine methyl ester with Boc-Pro-OH. It was crystallized from its solution in a methanol-water mixture at 4°C and the crystals belong to the orthorhfmbic space group P2,2,2, with a = 10.239( 1) A, b = 19.276(4) A, c = 20.31
