These effects mainly arise from the uncontrolled release of the hydrogen peroxide that is produced by the redox reaction involving l-amino acids catalyzed by these flavoenzymes. Taking their clinical relevance into account, few SV-LAAOs have been structurally characterized and the structural determinants responsible for their broad direct and indirect pharmacological activities remain unclear. In this work, an LAAO from Bothrops jararacussu venom (BJu-LAAO) was purified and crystallized. The BJu-LAAO crystals belonged to space group P21, with unit-cell parameters a similar to=similar to 66.38, b = 72.19, c = 101.53 angstrom, beta = 90.9 degrees. The asymmetric unit contained two similar to molecules and the structure was determined and partially refined at 3.0 angstrom resolution.211-213engl-amino acid oxidaseSnake venomArtigo10.1107/S1744309111054923WOS:000299948000023Acesso abertoWOS000299948000023.pdf91625089789458870000-0003-2460-1145
