CC -!- FUNCTION: Involved in the catabolism of homogentisate (2,5-
CC dihydroxyphenylacetate or 2,5-OH-PhAc), a central intermediate in the
CC degradation of phenylalanine and tyrosine. Catalyzes the oxidative ring
CC cleavage of the aromatic ring of homogentisate to yield
CC maleylacetoacetate. {ECO:0000255|HAMAP-Rule:MF_00334}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=homogentisate + O2 = 4-maleylacetoacetate + H(+);
CC Xref=Rhea:RHEA:15449, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379,
CC ChEBI:CHEBI:16169, ChEBI:CHEBI:17105; EC=1.13.11.5;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00334};
CC -!- COFACTOR:
CC Name=Fe cation; Xref=ChEBI:CHEBI:24875;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00334};
CC -!- PATHWAY: Amino-acid degradation; L-phenylalanine degradation;
CC acetoacetate and fumarate from L-phenylalanine: step 4/6.
CC {ECO:0000255|HAMAP-Rule:MF_00334}.
CC -!- SUBUNIT: Hexamer; dimer of trimers. {ECO:0000255|HAMAP-Rule:MF_00334}.
CC -!- SIMILARITY: Belongs to the homogentisate dioxygenase family.
CC {ECO:0000255|HAMAP-Rule:MF_00334}.
