This protein seems to be a 2Fe-2S ferredoxin. Aromatic compound metabolism; benzene degradation; catechol from benzene: step 1/2. This dioxygenase system consists of four proteins: the two subunits of the hydroxylase component (BedC1 and BedC2), a ferredoxin (BedB) and a ferredoxin reductase (BedA). Belongs to the bacterial ring-hydroxylating dioxygenase ferredoxin component family.
