Enzyme Information

1.13.11.3
Protocatechuate 3,4-dioxygenase.
based on mapping to UniProt P20371
3,4-dihydroxybenzoate + O(2) = 3-carboxy-cis,cis-muconate.
-!- 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.
