    1.5.1.20 | Fe2+ |
the enzyme dimer has 14.9 mol iron per mol enzyme, it possesses two 4Fe-4S-clusters |
764937 |
| 1.5.1.20 | Iron |
15.2 molecules iron per enzyme molecule, enzyme contains iron-sulfur clusters |
437713, 437714 |
| 1.5.1.20 | Iron |
the diheme electron transfer small subunit NapB binds to the large subunit with heme II in close proximity to the [4Fe-4S] cluster of NapA. The plasticity of the complex contributes to an efficient electron transfer in the complex from the heme I of NapB to the molybdenum catalytic site of NapA |
659990 |
| 1.5.1.20 | iron-sulfur centre |
enzyme contains 15.2 molecules iron and 19.5 molecules acid-labile sulfur as iron-sulfur clusters |
437713, 437714 |
| 1.5.1.20 | Molybdenum |
enzyme contains molybdenum. When molybdenum concentrations are limiting, molybdenum is involved in the regulation of the expression of the nap genes: the ModA mutant lacks both the 90000 Da protein corresponding to the NapA component of nitrate reductase, and the membrane-bound 25000 Da c-type cytochrome NaC |
657902 |
| 1.5.1.20 | Molybdenum |
the diheme electron transfer small subunit NapB binds to the large subunit with heme II in close proximity to the [4Fe-4S] cluster of NapA. The plasticity of the complex contributes to an efficient electron transfer in the complex from the heme I of NapB to the molybdenum catalytic site of NapA |

| 1.5.1.20 | more |
no evidence for participation of heavy metals ions in catalytic process |
392149 |
| 1.5.1.20 | more |
the enzyme dimer has 16.2 mol acid-labile sulfur per mol enzyme |
764937 |
| 1.5.1.20 | Zinc |
2.3 molecules zinc per enzyme molecule |
