Multiple amino acid sequence alignment of BlPLA2s with svPLA2s homologous. The one letter code for amino acid nomenclature is used. Proteins compared and their UniProt or GeneBank (GB) accession numbers: K49 (piratoxin II, P82287) from Bothrops pirajai: K49 (bthtx I, Q90249) from B. jararacussu: K49 (BlK-PLA2, P86975) from B. leucurus: K49 (myotoxin II, P24605) from B. asper: K49 (myotoxin II, Q91834) from B. moojeni: K49 (O57385) from Deinagkistrodon (formerly Agkistrodon) acutus: R49 (Q28681) from Protobothrops elegans: S49 (P48650) from Echis carinatus; D49 (BlD-PLA2, P86974) from B. leucurus: D49 (vipoxin complex, P04084) from Vipera ammodytes meridionalis: D49 (C9E7C4) from Crotalus durissus cascavella: D49 (Q7ZTA6) from C.v.viridis: D49 (Q2H228) from B. erythromelas: D49 (GB/KC544002) from B. neuwiedi: D49 (O42191) from Gloydius (formerly Agkistrodon) halys pallas. (*) is used for identical residues (:) for conserved ones and (.) for semi-conserved substitutions among all sequences in the alignment. Gaps were introduced to maximize the sequence homology, as indicated in part (A) and (B), respectively.
