Crystallization and preliminary X-ray studies of psophocarpin B1, a chymotrypsin inhibitor from winged bean seeds.

Abstract

Psophocarpin B1 is a 20,000 Mr protein of winged bean (Psophocarpus tetragonolobus) seeds having chymotrypsin inhibitory activity. Single crystals of this protein suitable for X-ray crystallographic studies have been obtained by the vapour diffusion method using ammonium sulphate. The crystals are hexagonal, space group P6(4)22 or P6(2)22, cell dimensions a… (More)
