Resumen
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Currently, Crotalus viridis was divided into two species: Crotalus viridis and Crotalus oreganus. The current classification divides 'the old' Crotalus viridis into two new and independent species: Crotalus viridis (subspecies: viridis and nuntius) and Crotalus oreganus (subspecies: abyssus, lutosus, concolor, oreganus, helleri, cerberus, and caliginis). The analysis of a product from cDNA (E6d), derived from the gland of a specie Crotalus viridis viridis, was found to produce an acid phospholipase A(2). In this study we isolated and characterized a PLA(2) (D49) from Crotalus oreganus abyssus venom. Our studies show that the PLA(2) produced from the cDNA of Crotalus viridis viridis (named E6d) is exactly the same PLA(2) primary sequence of amino acids isolated from the venom of Crotalus oreganus abyssus. Thus, the PLA(2) from E6d cDNA is actually the same PLA(2) presented in the venom of Crotalus oreganus abyssus and does not correspond to the venom from Crotalus viridis viridis. These facts highlight the importance of performing more studies on subspecies of Crotalus oreganus and Crotalus viridis, since the old classification may have led to mixed results or mistaken data.
