    L-amino acid oxidases (LAAOs) are dimeric flavoproteins that catalyze the deamination of L-amino acid to α-keto acid, producing ammonia and hydrogen peroxide. In this study, we report the crystal structure and molecular dynamics simulations of LAAO from the venom of Bothrops atrox (BatroxLAAO). BatroxLAAO presents several biological and pharmacological properties with promising biomedical applications. BatroxLAAO structure contains the highly conserved structural pattern of LAAOs comprising a FAD-binding domain, substrate-binding domain and helical domain, and a dimeric arrangement that can be stabilized by zinc. Also, molecular dynamics results show an asymmetric behavior, and a direct communication between FAD- and substrate-binding domains of counterpart subunits. These findings shed light on the structural role of dimerization to catalytic mechanism of SV-LAAOs.
