Abstract
The ccoNOQP gene cluster of Rhodobacter sphaeroides 2.4.1T encodes a cbb3 cytochrome oxidase which is utilized in oxygen-limited conditions for aerobic respiration. The beta-galactosidase activity of a ccoN::lacZ transcriptional fusion was low under high (30%)-oxygen and anaerobic growth conditions. Maximal ccoN::lacZ expression was observed when the oxygen concentration was lowered to 2%. In an FnrL mutant, ccoN::lacZ expression was significantly lower than in the wild-type strain, suggesting that FnrL is a positive regulator of genes encoding the cbb3 oxidase.
摘要
球形红细菌2.4.1T的ccoNOQP基因簇编码一种cbb3细胞色素氧化酶，该酶在氧限制条件下用于有氧呼吸。在高氧（30%）和厌氧生长条件下，ccoN::lacZ转录融合体的β-半乳糖苷酶活性较低。当氧浓度降至2%时，观察到ccoN::lacZ的最大表达。在FnrL突变体中，ccoN::lacZ的表达明显低于野生型菌株，这表明FnrL是编码cbb3氧化酶基因的正调控因子。
