CRYSTALLIZATION AND PRELIMINARY X-RAY STUDIES OF PSOPHOCARPIN B1, A CHYMOTRYPSIN INHIBITOR FROM WINGED BEAN SEEDS
OverviewOverview
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.
