Sysname
3,4,5-trihydroxybenzoate:oxygen oxidoreductase
Reaction(IUBMB)
3,4,5-trihydroxybenzoate + O2 = (1E)-4-oxobut-1-ene-1,2,4-tricarboxylate [RN:
R09565 ]
Reaction(KEGG)
Substrate
Product
(1E)-4-oxobut-1-ene-1,2,4-tricarboxylate [CPD:
C04434 ]
Comment
Contains non-heme Fe2+. The enzyme is a ring-cleavage dioxygenase that acts specifically on 3,4,5-trihydroxybenzoate to produce the keto-tautomer of 4-oxalomesaconate [1,2].
