Description
Protocatechuate 3,4-dioxygenase catalyzes the convertion of 3,4-dihydroxybenzoic acid and O2 to 3-carboxy-cis,cis-muconate. Dioxygenases are oxydoreductase enzymes. They utilize a dioxygen (O2) molecule as an oxidant. As opposed to monooxygenases, in dioxygenases reactions both atoms from O2 are incorporated into the substrate. Protocatechuate dioxygenase from P. putida has a molecular weight of 200,000 daltons and contains 4 alpha subunits of 23,000 daltons, 4 beta subunits of 26,500 daltons, and 4 ferric irons, suggesting that the enzyme is a tetramer of (𝛂𝛃Fe3+) catalytic units.
Notes
None.
