Oxidation of benzylamine by MAO results in an accumulation of GSSG in mouse liver mitochondria. Formation of GSSG is prevented by deprenyl, an inhibitor of MAO-B, but not by catalase. GSSG accumulation also occurs with dopamine as substrate. Oxidation of monoamines by mitochondrial MAO represents a potential oxidant stress for mitochondria.
单胺氧化酶(MAO)氧化苄胺会导致小鼠肝线粒体中氧化型谷胱甘肽(GSSG)的积累。MAO-B的抑制剂司来吉兰可防止GSSG的形成,但过氧化氢酶不能。以多巴胺为底物时也会发生GSSG积累。线粒体MAO对单胺的氧化是线粒体潜在的氧化应激。
