“…moojeni venom [ 33 , 86 ] was higher among males’ venoms, and it was observed in this work only with Bm1 (no statistical difference) and Bm3. Snake venom PLA 2 s from the Viperidae family can be divided into two groups: catalytically active (D-49) and enzymatically inactive (K-49, S-49, R-49, Q-49 and N-49) [ 79 , 92 , 93 ]. The presence of both types of PLA 2 s in different proportions and the variability of catalytic efficiency (specific activity) could explain why the PLA 2 activity in the enzymatic assays did not reflect the increase of PLA 2 found in LC-MS/MS [ 94 , 95 ].…”

“…Também há um aumento da concentração de LAAO, resultado já esperado devido ao fato que já havia sido notado uma intensificação da coloração amarela nos venenos e também o aumento gradual da atividade de LAAO conforme os animais ficavam mais velhos. Os efeitos relacionados às LAAOs são creditados ao H2O2 produzido durante sua reação enzimática, que é responsável por ações como miotoxicidade, hemorragia, edema, citotoxicidade e hemólise (ANDE et al, 2006;CISCOTTO et al, 2009;DU;CLEMETSON, 2002;PIŠLAR et al, 2016;RODRIGUES et al, 2009) SANTOS et al, 2011;RODRIGUES et al, 2020;YAMAZAKI;HYODO;MORITA, 2003). Em um veneno pode haver diferente proporções entre esses tipos de PLA2s e diferenças em sua eficiência catalítica (atividade específica), podendo resultar em um veneno com baixa atividade enzimática mesmo que com grande concentração dessa proteína (LOMONTE et al, 2020;VITORINO et al, 2020).…”
