CRYSTALLIZATION AND PRELIMINARY X-RAY STUDIES OF PSOPHOCARPIN B1, A CHYMOTRYPSIN INHIBITOR FROM WINGED BEAN SEEDS
Overview
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 = b = 61 A, c = 210 A. They are stable to irradiation with X-rays and diffract to at least 2.6 A resolution.
About this Structure
1WBC is a Single protein structure of sequence from Psophocarpus tetragonolobus. Full crystallographic information is available from OCA.
