| 2.8.1.6 | Iron |
1 [2Fe-2S] and 1 [4Fe-4S] cluster per monomer are essential for optimal activity |

| 2.8.1.6 | Iron |
1 [2Fe-2S] cluster per monomer, but enzyme can be reconstituted to contain an additional [4Fe-4S] cluster, both clusters must be present for tight substrate binding |

| 2.8.1.6 | Iron |
1 [2Fe-2S] per monomer, but enzyme is more active when reconstituted with an additional [4Fe-4S] cluster |

| 2.8.1.6 | Iron |
aerobically purified enzyme contains 1.2-1.5 [2Fe-2S] clusters per monomer. Upon reduction the [Fe2-S2] clusters are converted to [Fe4-S4] clusters. The dominant stable cluster state for the enzyme is a dimer containing 2 [Fe2-S2] clusters and 2 [Fe4-S4] clusters |

| 2.8.1.6 | FeCl3 |
binds 1 [Fe4-S4] cluster per monomer |

| 2.8.1.6 | Iron |
BioB appears to be resistant to degradation and capable of multiple turnovers only under high-iron conditions that favor repair of the FeS clusters, a process most likely mediated by the Isc or Suf iron-sulfur cluster assembly systems. |
