IUBMB Enzyme Nomenclature

EC 4.1.1.103

Accepted name: γ-resorcylate decarboxylase

Reaction: 2,6-dihydroxybenzoate = 1,3-dihydroxybenzene + CO2

Glossary: 2,6-dihydroxybenzoate = γ-resorcylate
1,3-dihydroxybenzene = resorcinol

Other name(s): graF (gene name); tsdA (gene name)

Systematic name: 2,6-dihydroxybenzoate carboxy-lyase

Comments: The enzyme, characterized from several bacterial strains, is involved in the degradation of γ-resorcylate. It contains a zinc ion and a water molecule at the active site. The reaction is reversible, but equilibrium greatly favors the decarboxylation reaction.
