ccmA | ccmB | b2201 | b2200 | Heme export ABC transporter ATPase; Part of the ABC transporter complex CcmAB involved in the biogenesis of c-type cytochromes; once thought to export heme, this seems not to be the case, but its exact role is uncertain.

ccmA | napA | b2201 | b2206 | Heme export ABC transporter ATPase; Part of the ABC transporter complex CcmAB involved in the biogenesis of c-type cytochromes; once thought to export heme, this seems not to be the case, but its exact role is uncertain. Responsible for energy coupling to the transport system. | Nitrate reductase, periplasmic, large subunit; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family. NasA/NapA/NarB subfamily. | 0.841 |
ccmA | napB | b2201 | b2203 | Heme export ABC transporter ATPase; Part of the ABC transporter complex CcmAB involved in the biogenesis of c-type cytochromes; once thought to export heme, this seems not to be the case, but its exact role is uncertain. Responsible for energy coupling to the transport system. | Nitrate reductase, small, cytochrome C550 subunit, periplasmic; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from the membrane-anchored tetraheme c-type NapC protein and transfers these to NapA subunit, thus allowing electron flow between membrane and periplasm. Essential for periplasmic nitrate reduction with nitrate as the terminal electron acceptor; Belongs to the NapB family. | 0.899 |
ccmA | napC | b2201 | b2202 | Heme export ABC transporter ATPase; Part of the ABC transporter complex CcmAB involved in the biogenesis of c-type cytochromes; once thought to export heme, this seems not to be the case, but its exact role is uncertain.

Responsible for energy coupling to the transport system. | Assembly protein for periplasmic nitrate reductase; 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. May have a role in the insertion of the NapA molybdenum cofactor. | 0.807 |

Responsible for energy coupling to the transport system. | Ferredoxin-type protein, role in electron transfer to periplasmic nitrate reductase NapA; Could be involved in the maturation of NapA, the catalytic subunit of the periplasmic nitrate reductase, before its export into the periplasm. Is not involved in the electron transfer from menaquinol or ubiquinol to the periplasmic nitrate reductase. | 0.818 |
