FIG. 1.
Outlines of anaerobic metabolism of phenol, as studied for the denitrifying bacterium T. aromatica (20). The proposed reaction scheme for phenylphosphate synthase is hypothetical and is studied here. E1, phenylphosphate synthase studied here; E2, phenylphosphate carboxylase; Fdred, reduced ferredoxin; E3, 4-hydroxybenzoate-coenzyme A (CoA) ligase (AMP forming); E4, 4-hydroxybenzoyl-CoA reductase (dehydroxylating); E5, benzoyl-CoA reductase (aromatic ring reducing).
