Membrane-bound nitrate reductase | narG, narH, narJ, narI, narZ, narY, narW, narV | 1.7.5.1 | K00370 K00371 K00373 K00374 | A membrane-bound enzyme which supports anaerobic respiration on nitrate under anaerobic conditions and in the presence of nitrate. Contains the bicyclic form of the molybdo-bis(molybdopterin guanine dinucleotide) cofactor, iron-sulfur clusters and heme b. Escherichia coli expresses two forms NarA and NarZ, both being comprised of three subunits. | Link |
Periplasmic nitrate reductase (cytochrome) | napA, napB | 1.9.6.1 | K02567 K02568 K02569 K02570 | periplasmic nitrate reductase complex (NapAB) mainly catalyzes the initial reduction of nitrate to nitrite | Link |
Ntrite reductase (cytochrome c-552) | nrfA | 1.7.2.2 | K03385 | Nitrite reduction to ammonium is mediated by a pentaheme cytochrome C nitrite reductase (NrfA) and is carried out without producing any intermediate N compound | Link |
cytoplasmic NADH-dependent nitrite reductase | nirB nirD |
1.7.1.15 | K00362 | Nitrite reduction to ammonium and is carried out without producing any intermediate N compound | Link |
Cytochrome P450 nitric oxide reductase | P450nor | 1.7.1.14 | K15877 | nitric oxide reductase [NAD(P)+, nitrous oxide-forming] is responsible for reduction of nitric oxide to N2O | Link |
Nitrite reductase (NO-forming) | nirK | 1.7.2.1 | K00368 | nirK is a copper-containing nitrite reductase (CuNiR) and a key catalytic enzyme in the environmental denitrification process that helps to produce nitric oxide from nitrite, molecular mechanism of denitrification process. | Link |
