   1.12.1.4 | 4Fe-4S-center |
displays electron paramagnetic resonance signals characteristic of oxidized [3Fe-4S]+ cluster. Cysteine residues C302, C353, and C356 are strictly required for the binding of the [4Fe-4S] cluster, whereas the fourth ligand of the coordination sphere can vary depending on the molecular environment created by local residues and/or experimental conditions |

subunit HydA (63 kDa) is predicted to harbor the H cluster, i.e., the [6Fe4S] hydrogenase active site, three [4Fe4S] clusters, and one [2Fe2S] cluster. Subunit HydB (67 kDa) is predicted to harbor three [4Fe4S] clusters, a flavin binding site, and an NAD binding site. HydC (17 kDa) is predicted to harbor one [2Fe2S] cluster |
