Summary
NarI is involved in localizing NarGHI to the membrane Induced by anaerobiosis plus nitrate. [More information is available at EcoGene: EG10640]. The subunit of nitrate reductase A is a membrane-embedded heme-iron subunit resembling cytochrome b, which transfers electrons from the quinone pool to the subunit. [More information is available at EcoCyc: EG10640].
