General annotation (Comments)

Function

Nitrate reductase is a key enzyme involved in the first step of nitrate assimilation in plants, fungi and bacteria.

Catalytic activity

Nitrite + NAD(P)+ + H2O = nitrate + NAD(P)H.

Cofactor

Binds 1 FAD.

Binds 1 heme group. The heme group is called cytochrome b-557.

Binds 1 molybdenum ion.

Subunit structure

Homodimer By similarity.

Sequence similarities

Belongs to the nitrate reductase family.

Contains 1 cytochrome b5 heme-binding domain.

Contains 1 FAD-binding FR-type domain.
