the enzyme-bound complex can be described as an [NiFe3-4S4]-acetyl complex |

| 2.3.1.169 | Fe |
the multienzyme complex contains at least two protein components: a CO-oxidizing Ni/Fe-S component and a cobalt-containing Co/Fe-S component |

| 2.3.1.169 | Fe |
the Ni-Fe4S4-5C cluster of enzyme catalyses the reversible reduction of CO2 to CO and is located in the beta-subunit. |

| 2.3.1.169 | Fe2+ |
a [Fe4S4] cluster |

| 2.3.1.169 | Fe2+ |
Fe/S-containing active site metal center, the A cluster |

| 2.3.1.169 | Fe2+ |
the enzyme has a metallocofactor containing iron, sulfur, copper, and nickel, the cofactor responsible for the assembly of acetyl-CoA contains a [Fe4S4] cubane bridged to a copper-nickel binuclear site |

| 2.3.1.169 | Iron |
binding of Ni to the A-cluster slows the reduction kinetics of the [Fe4S4]2+ cubane. An upper limit of two electrons per a subunit are transferred from titanium(III) citrate to the Ni subcomponent of the A-cluster during reductive activation. These electrons are accepted quickly relative to the reduction of the [Fe4S4]2+ cubane. This reduction is probably a prerequisite for methyl group transfer |

| 2.3.1.169 | Iron |
protein contains in average 3.7 Fe atoms and 1.6 Ni atoms per monomer molecule, which is consistent with the presence of a [NipNid]-[Fe4S4]-center |
