IUBMB Enzyme Nomenclature


Accepted name: phenol phosphorylase

Reaction: ATP + phenol + H2O = AMP + phenyl phosphate + phosphate

Other name(s): phenylphosphate synthase

Systematic name: ATP:phenol phosphotransferase (AMP-forming)

Comments: The enzyme, characterized from the bacterium Thauera aromatica, catalyses the first step in an anaerobic phenol degradation pathway. The enzyme, composed of three subunits, transfers the β-phosphoryl from ATP to phenol, forming phenyl phosphate, AMP, and phosphate [1]. During catalysis a diphosphoryl group is transferred from ATP to a histidine residue in one of the enzyme's subunits, from which phosphate is cleaved to render the reaction unidirectional. The remaining histidine phosphate subsequently serves as the actual phosphorylation agent [2].
