ENZYME entry: EC 1.13.11.2

Accepted Name
Catechol 2,3-dioxygenase.
Alternative Name(s)
2,3-pyrocatechase.
Cato2ase.
Metapyrocatechase.
Reaction catalysed
Catechol + O(2) <=> 2-hydroxymuconate semialdehyde
Cofactor(s)
Iron.
Comment(s)
  • The enzyme from Alcaligenes sp. strain O-1 has also been shown to catalyze the reaction: 2,3-dihydroxybenzenesulfonate + O(2) + H(2)O = 2-hydroxymuconate + bisulfite and has been referred to as 2,3- dihydroxybenzenesulfonate 2,3-dioxygenase.
  • Further work will be necessary to show whether or not this is a distinct enzyme.
  • Formerly EC 1.13.1.2.
