FES 5006 x

Metal-MACiE entry for FES 5006 x

The enzyme is an hetero dimer with a reduced molybdenum bis(molybdopterin) center (L2Mo=O) and a [3Fe-4S] cluster in the larger subunit and a [2Fe-2S] Rieske cluster in the smaller subunit (PMID14769044). This is the Rieske-type iron-sulfur cluster and it appears to play a role in electron transfer to the external azurin (PMID12236735).
