PHOSPHOLIPASE A2 INHIBITOR FROM VIPOXIN
OverviewOverview
The high resolution crystal structure of a natural PLA2 inhibitor has been, determined by Patterson search methods. In the heterodimeric, neurotoxic, complex, vipoxin, isolated from the venom of Bulgarian viper, PLA2, inhibitor represents the non-toxic subunit. The model was refined to a, crystallographic R-factor of 15.5% for data between 6 and 1.76 A, resolution. The packing of the inhibitor in the crystal reveals close, contacts between the molecules, which are symmetry-related by the 2-fold, axes of the lattice. These pairs associate as a crystallographic dimer, stabilized by a set of interactions, including van der Waals contacts, between residues from symmetry-related pairs, denoted as the recognition, site and the recognition surface. Residues Ph3, Trp31 and Tyr119 represent, the ... [(full description)]
