ACIDIC PHOSPHOLIPASE A2 FROM VENOM OF OPHIOPHAGUS HANNAH
Overview
The crystal structure of an acidic phospholipase A(2) from Ophiophagus, hannah (king cobra) has been determined by molecular replacement at 2.6-A, resolution to a crystallographic R factor of 20.5% (R(free)=23.3%) with, reasonable stereochemistry. The venom enzyme contains an unusual, "pancreatic loop." The conformation of the loop is well defined and, different from those in pancreas PLA(2), showing its structural, variability. This analysis provides the first structure of a PLA(2)-type, cardiotoxin. The sites related to the cardiotoxic and myotoxic activities, are explored and the oligomer observed in the crystalline state is, described.
