Crystal Structure of BthTX-II (Asp49-PLA2 from Bothrops jararacussu snake venom) with calcium ions

Template:ABSTRACT PUBMED 20878713

Function

[PA2B2_BOTJR] Snake venom phospholipase A2 (PLA2) that shows a moderate enzymatic activity. It induces indirect hemolytic, anticoagulant, and cytotoxic activities. In vivo, it induces muscle necrosis, accompanied by polymorphonuclear cell infiltration, and edema in the mouse paw. PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides.^{[1] [2]}
