Denitrification system component NapC/NirT/NrfH (IPR024717)

Short name: NapC/NirT/NrfH

Overlapping homologous superfamilies

Family relationships


This family includes NapC, a predicted membrane-anchored four-heme c-type cytochrome that forms one component of the periplasmic nitrate reductase along with NapA, NapB, NapD, NapE, and NapF subunits. The family also includes the nitrite reductase component NirT, and NrfH - a subunit of the nitrite reductase complex that mediates electron transfer from quinol to the catalytic subunit [PMID: 10672190].
