ENZYME entry: EC 1.13.11.3

Accepted Name
protocatechuate 3,4-dioxygenase
Alternative Name(s)
protocatechuate oxygenase
Reaction catalysed
3,4-dihydroxybenzoate + O2 <=> 3-carboxy-cis,cis-muconate + 2 H(+)
Comment(s)
  • The enzyme, which participates in the degradation of aromatic compounds, catalyzes the intradiol addition of both oxygen atoms from molecular oxygen, resulting in ortho-cleavage of the aromatic ring.
  • The type of cleavage leads to mineralization via the intermediate 3-oxoadipate.
  • Formerly EC 1.13.1.3 and EC 1.99.2.3.
