General annotation (Comments)

Function

Involved in the catabolism of homogentisate (2,5-dihydroxyphenylacetate or 2,5-OH-PhAc), a central intermediate in the degradation of phenylalanine and tyrosine. Catalyzes the oxidative ring cleavage of the aromatic ring of homogentisate to yield maleylacetoacetate By similarity. HAMAP-Rule MF_00334

Catalytic activity

Homogentisate + O2 = 4-maleylacetoacetate. HAMAP-Rule MF_00334

Cofactor

Iron By similarity. HAMAP-Rule MF_00334

Pathway

Amino-acid degradation; L-phenylalanine degradation; acetoacetate and fumarate from L-phenylalanine: step 4/6. HAMAP-Rule MF_00334

Subunit structure

Hexamer; dimer of trimers By similarity. HAMAP-Rule MF_00334

Sequence similarities

Belongs to the homogentisate dioxygenase family.
