CC   -!- FUNCTION: Involved in resorcinol degradation (Ref.2). Catalyzes the
CC       conversion of hydroxyquinol to malelylacetate (Ref.2). Shows also weak
CC       activity with catechol, 3-methylcatechol and 4-methylcatechol, but
CC       cannot use 4-chlorocatechol, 4-nitrocatechol or protocatechuate
CC       (Ref.2). {ECO:0000269|Ref.2}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=benzene-1,2,4-triol + O2 = 2 H(+) + maleylacetate;

CC       Name=Fe(3+); Xref=ChEBI:CHEBI:29034;
CC         Evidence={ECO:0000250|UniProtKB:Q5PXQ6};
CC       Note=Binds 1 Fe(3+) ion per subunit. {ECO:0000250|UniProtKB:Q5PXQ6};
CC   -!- PATHWAY: Aromatic compound metabolism. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the intradiol ring-cleavage dioxygenase family.
CC       {ECO:0000305}.
