Specific function: Small subunit of the periplasmic nitrate reductase (NAP). Only expressed at high levels during aerobic growth. NapAB complex receives electrons from the membrane-anchored tetraheme NapC protein, thus allowing electron flow between membrane and periplasm.

COG id: COG3043

COG function: function code C; Nitrate reductase cytochrome c-type subunit
