   4.2.1.167 | 4Fe-4S centre |
the enzyme contains two [4Fe4S]2+ clusters. It is likely that the alpha and beta subunits are bridged by a [4Fe4S]2+ cluster. The enzyme contains 7.5 non-heme iron and 8.1 acid labile sulfur/heterodimer, symmetric cube-type structures |

| 4.2.1.167 | Molybdenum |
protein contains about 0.1 molybdenum (VI) per heterodimer. The enzyme has to be activated by the extremely oxygensensitive [4Fe-4S]1+/2+-cluster-containing homodimeric component A, which generates Mo(V) by an ATP/Mg2+-induced one-electron transfer |
