Abstract:

Phospholipases D are the major dermonecrotic component of Loxosceles venom and catalyze the hydrolysis of phospholipids, resulting in the formation of lipid mediators such as ceramide-1-phosphate and lysophosphatidic acid which can induce pathological and biological responses. Phospholipases D can be classified into two classes depending on their catalytic efficiency and the presence of an additional disulfide bridge. In this work, both wild-type and H12A-mutant forms of the class II phospholipase D from L. intermedia venom were crystallized. Wild-type and H12A-mutant crystals were grown under very similar conditions using PEG 200 as a precipitant and belonged to space group P12(1)1, with unit-cell parameters a = 50.1, b = 49.5, c = 56.5 A, beta = 105.9 degrees . Wild-type and H12A-mutant crystals diffracted to maximum resolutions of 1.95 and 1.60 A, respectively.
