Accepted name: 4-hydroxybenzoyl-CoA reductase

Reaction: benzoyl-CoA + oxidized ferredoxin + H2O = 4-hydroxybenzoyl-CoA + reduced ferredoxin

Other name(s): 4-hydroxybenzoyl-CoA reductase (dehydroxylating); 4-hydroxybenzoyl-CoA:(acceptor) oxidoreductase; benzoyl-CoA:acceptor oxidoreductase

Systematic name: benzoyl-CoA:oxidized ferredoxin oxidoreductase

Comments: A molybdenum-flavin-iron-sulfur protein that is involved in the anaerobic pathway of phenol metabolism in bacteria. A ferredoxin with two [4Fe-4S] clusters functions as the natural electron donor [3].
