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. |
