A proteinase, named BmooMPα-I, from the venom of Bothrops moojeni, was purified by DEAE-Sephacel, Sephadex G-75 and heparin-agarose column chromatography. The enzyme was purified to homogeneity as judged by its migration profile in SDS–PAGE stained with coomassie blue, and showed a molecular mass of about 24.5kDa. Its complete cDNA was obtained by RT-PCR and the 615bp codified for a mature protein...
Snake venoms are known to be an extensive source of bioactive peptides. Bradykinin-potentiating peptides (BPPs) are inhibitors of the angiotensin-converting enzyme that have already been identified in the venom of many snake, scorpion, spider and batrachian species. Their most characteristic structural features are an invariable N-terminal pyroglutamate residue (pGlu or Z) and two consecutive proline...
Phospholipase A 2 (PLA 2 , EC 3.1.1.4), a major component of snake venoms, specifically catalyzes the hydrolysis of fatty acid ester bonds at position 2 of 1,2-diacyl-sn-3-phosphoglycerides in the presence of calcium. This article reports the purification and biochemical/functional characterization of BmooTX-I, a new myotoxic acidic phospholipase A 2 from Bothrops moojeni snake...
