Biochemical and structural investigations of Bothropstoxin-II, a myotoxic Asp49 phospholipase A(2) from Bothrops jararacussu venom

Abstract

Bothropstoxin-II a calcium-dependent enzyme from Bothrops jararacussu venom causes tissue damage and several haemostatic disorders including platelet aggregation. In order to elucidate the structural determinants of its multiple pharmacological activities, we have studied the effects of suramin on Bothropstoxin-II and present details concerning the mode of binding.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES
