Protein
Nitrite transporter NirC
Organism
Escherichia coli (strain K12)
Function
Catalyzes nitrite uptake and nitrite export across the cytoplasmic membrane. Is up to 10-fold more active than NarK or NarU in nitrite uptake for subsequent reduction in the cytoplasm by the NirB/NirD nitrite reductase.
Similarity
Belongs to the FNT transporter (TC 2.A.44) family.
