OXIDATIVE METABOLIC ENZYMES NADH PEROXIDASE, NADH OXIDASE

肠道兼性厌氧菌，如粪肠球菌， 是过氧化氢酶阴性的表型，缺乏血红素 生物合成。虽然它们也缺乏呼吸细胞色素，但S。 粪便利用氧气来提高生长产量。这些生物体 完全依赖于底物水平的磷酸化来合成和 利用新的黄素酶作为氧化还原酶。一种对 构成E的许多元素的结构组织。 粪便的新陈代谢和调节将使我们更清楚地了解 它们的增殖机制。这些黄素相关基因的作用 肠球菌氧化代谢中的酶及其对 它们的扩散可能会为限制 被这些微生物感染。

The enteric facultative anaerobes, such as Enterococcus faecalis, are catalase-negative phenotypes and are deficient in heme biosynthesis. Although they also lack respiratory cytochromes, the S. faecalis utilizes oxygen to enhance growth yields. These organisms rely entirely on substrate-level phosphorylation for ATP synthesis and utilizes novel flavoenzymes as oxidoreductases. An understanding of the structural organization of many of the elements contributing to E. faecalis metabolism and regulation would give a clearer picture of their proliferative mechanism. The roles of these flavin-linked enzymes in enterococcal oxidative metabolism and their contribution to their proliferation may yield insight to novel approaches of limiting infection by these organisms.
