PHOSPHOLIPASE A2 MODIFIED BY PBPB
Overview
The crystal structure of acidic phospholipase A2 (APLA2) from Agkistrodon, halys pallas covalently modified by p-bromo-phenacyl-bromide (pBPB) was, determined to a resolution of 2.0 A by an isomorphous difference Fourier, method with the native APLA2 structure as an initial model and refined to, a crystallographic R factor of 15.3%. The modified APLA2 structure is, remarkably similar to that of the native one. Least-squares superposition, of C alpha atoms of native and modified APLA2 results in a, root-mean-square coordinate deviation of 0.243 A. The p-bromo-phenacyl, group near the active site occupies a position similar to that in pBPB, modified bovine pancreatic PLA2. The inhibitor covalently bound to the NDI, atom of His48 fits well in the hydrophobic channel, forming extensive, ... [(full description)]
