A structure based model for liposome disruption and the role of catalytic activity in myotoxic phospholipase A(2)S
(Elsevier B.V., 2003-12-15)
Venom phospholipase A(2)s (PLA(2)s) display a wide spectrum of pharmacological activities and, based on the wealth of biochemical and structural data currently available for PLA(2)S, mechanistic models can now be inferred ...

Crytallization and high-resolution X-ray diffraction data collection of an Asp49 PLA(2) from Bothrops jararacussu venom both in the presence and absence of Ca2+ ions
(Elsevier B.V., 2004-12-01)
Snake venom PLA(2)s have been extensively studied due to their role in mediating and disrupting physiological processes such as coagulation, platelet aggregation and myotoxicity. The Ca2+ ion bound to the putative ...
Comparison between apo and complexed structures of bothropstoxin-I reveals the role of Lys122 and Ca2+-binding loop region for the catalytically inactive Lys49-PLA(2)s
(Academic Press Inc. Elsevier B.V., 2010-07-01)
Phospholipases A(2) (Asp49-PLA(2)s) are enzymes responsible for cellular membrane disruption through Ca2+-dependent hydrolysis of phospholipids. A class of these proteins (Lys49-PLA(2)s) does not show catalytic activity ...

Ação do extrato bruto da Tabernaemontana catharinensis e de seu alcalóide isolado sobre as atividades de fosfolipases A2 ofídicas em preparação neuromuscular de camundongos
(Universidade Estadual Paulista (Unesp), 2011-10-07)
As fosfolipases A2 (PLA2s) estão entre os principais componentes de venenos ofídicos, podendo representar até 60 % do conteúdo protéico destas secreções em algumas espécies. As clássicas (PLA2s Asp49) são enzimas dependentes ...

Hyperalgesia induced by Asp49 and Lys49 phospholipases A2 from Bothrops asper snake venom: pharmacological mediation and molecular determinants
(2003-05)
The ability of Lys49 and Asp49 phospholipases A2 (PLA2), from Bothrops asper snake venom, to cause hyperalgesia was investigated in rats, using the paw pressure test. Intraplantar injection of both toxins (5–20 μg/paw) ...
