| cymA | napB | SO_4591 | SO_0845 | Membrane anchored tetraheme cytochrome c CymA. | Periplasmic nitrate reductase cytochrome c subunit NapB; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from the membrane-anchored tetraheme c-type CymA protein and transfers these to NapA subunit, thus allowing electron flow between membrane and periplasm. Not essential for nitrate reduction but confers advantage to the organism when grown on nitrate and thereby a fitness gain in utilizing nitrate. Belongs to the NapB family. | 0.989 |
| cymA | napD | SO_4591 | SO_0849 | Membrane anchored tetraheme cytochrome c CymA. | Periplasmic nitrate reductase chaperone NapD; Chaperone for NapA, the catalytic subunit of the periplasmic nitrate reductase. It binds directly and specifically to the twin- arginine signal peptide of NapA, preventing premature interaction with the Tat translocase and premature export. | 0.935 |
