HcbA1 is a unique flavoenzyme that catalyzes the first step in the bacterial hexachlorobenzene catabolic pathway. Here we report in vitro reconstitution of the HcbA1-catalyzed reaction. Detailed mechanistic studies provide evidence for nucleophilic aromatic substitution and flavin-N5-oxide formation.
HcbA1 是一种独特的黄素酶,催化细菌六氯苯代谢途径的第一步。在这里,我们报告了体外重建 HcbA1 催化反应的结果。详细的机理研究为亲核芳香取代和黄素-N5-氧化物形成提供了证据。
