Abstract: In this paper we reported the purification, the biological characterization and the amino acid sequence of two new isoforms basic 6-1 (Bj-IV) and 6-2 (Bj-V) PLA(2) D49 purified from the Bothrops jararacussu venom The isoforms 6-1 and 6-2 had a sequence of amino acids of 121 amino acid residues 6-1: DLFEWGQMIL KETGKNPFPY YGAYGCYCGW GGRGKPKDKD TDRCCYVHDC CYKKLTGCPK TDDRYSYSWL DLTIVCGEDD PCKELCECDK AIAVCFRENL GTYNKKYRYH LKPCKKADKP C and pI value 7.83 and 6-2: DLWQFGQMIL KETGKIPFPY YGAYGCYCGW GGRGGKPKDG TDRCCYVHDC CYKKLTGCPK TDDRYSYSWL DLTIVCGEDD PCKELCECDK AIAVCFRENL GTYNKKYRYH LKPCKKADKP C with a pI value of 7.99 Skeletal muscle preparations from the young chicken have been used previously in order to study the effects of toxins on neuromuscular transmission, providing an important opportunity to study the differentiated behavior of a toxin before more than one model, because it shows differences in its sensibilities Both isoforms have produced neuromuscular blockade in young chicken biventer cervicis nerve-muscle preparations in presence or absence of crotapotin crotalic (F3 and F4) indicating that catalytic activity was not essential for neuromuscular action in this preparation.
