Enzyme Information

1.7.99.4

Nitrate reductase.

based on mapping to UniProt P11349

Nitrite + acceptor = nitrate + reduced acceptor.

-!- The Pseudomonas enzyme is a cytochrome, but the enzyme from Micrococcus halodenitrificans is an iron protein containing molybdenum. -!- Reduced benzyl viologen and other dyes bring about the reduction of nitrate.
