BASIC PHOSPHOLIPASE A2 FROM AGKISTRODON HALYS PALLAS-IMPLICATIONS FOR ITS ASSOCIATION AND ANTICOAGULANT ACTIVITIES BY X-RAY CRYSTALLOGRAPHY
Overview
The basic phospholipase A2 (PLA2) from the venom of Agkistrodon halys, Pallas is a potent hemolytic toxin and anticoagulant. Crystal structure of, the enzyme complexed with detergent n-octyl beta-D-glucopyranoside, (beta-OG) in monoclinic crystal form has been determined to 2.6 A, resolution. Beta-OG molecules were found in the hydrophobic channels of, the enzyme. SDS-PAGE and dynamic light scattering measurements showed that, the enzyme had a strong tendency to dimerise in aqueous solution. In the, crystal structure the enzyme molecules associate into a tetramer with, pseudo 222 symmetry, and the interfacial recognition site linked dimers, constituting the tetramer have intensive interface interactions, and may, be stable in solution. The structure reveals a unique positively charged, ... [(full description)]
