IUBMB Enzyme Nomenclature

EC 4.1.1.123

Accepted name: phenyl-phosphate phosphatase/carboxylase

Reaction: 4-hydroxybenzoate + phosphate = phenyl phosphate + CO2 + H2O

Other name(s): phenyl phosphate carboxylase

Systematic name: 4-hydroxybenzoate carboxy-lyase (phenyl phosphate-forming)

Comments: The enzyme, characterized from the bacterium Thauera aromatica, participates in an anaerobic phenol degradation pathway. It catalyses the para dephosphorylation and carboxylation of phenylphosphate to 4-hydroxybenzoate. The enzyme from Thauera aromatica consists of four different subunits and requires K+ and a divalent metal cation (Mg2+ or Mn2+) for activity. It is strongly inhibited by oxygen.
