IUBMB Enzyme Nomenclature


Accepted name: nitrate reductase

Reaction: nitrite + acceptor = nitrate + reduced acceptor

Other name(s): respiratory nitrate reductase; nitrate reductase (acceptor); nitrite:(acceptor) oxidoreductase

Systematic name: nitrite:acceptor oxidoreductase

Comments: 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.
