Multiple alignment of the N-terminal sequence of the PLA₂ from B. atrox venom with other acidic PLA₂s from snake venoms. The highlighted amino acid residues are part of disulfide bonds (yellow) and the catalytic site (red). GI numbers (from top to bottom, respectively): 129420, 528050010, 387537880, 387537878, 123907441, 3914270, 23396779, 458601843 and 403399514. (*) indicates positions with fully conserved amino acid residues; (:) indicates conservation of the following groups with high score: K/R/Q/H, S/A, K/N/D, F/L/V/I, E/D/N/Q, T/S/A, I/M/L; (.) indicates conservation of the following groups with lowest score: N/R/G, G/D/N, A/V/T, Q/K/E/R, S/K/G/A, D/K/H, C/S, T/P
