cytochrome c-type protein NapB [Escherichia coli O157:H7 str. Sakai]

Protein Classification

nitrate reductase cytochrome c-type subunit( domain architecture ID 10013838)

electron transfer subunit (NapB) of the periplasmic nitrate reductase complex NapAB receives electrons from the membrane-anchored tetraheme c-type NapC protein and transfers these to the NapA subunit, allowing electron flow between membrane and periplasm
