Names and origin

Protein namesRecommended name:
Homogentisate 1,2-dioxygenase
EC=1.13.11.5
Alternative name(s):
Homogentisate oxygenase
Homogentisic acid oxidase
Homogentisicase
Gene names
Name:Hgd
Synonyms:Aku, Hgo
OrganismMus musculus (Mouse) [Reference proteome]
Taxonomic identifier10090 [NCBI]
Taxonomic lineageEukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Mammalia › Eutheria › Euarchontoglires › Glires › Rodentia › Sciurognathi › Muroidea › Muridae › Murinae › Mus › Mus

Protein attributes

Sequence length445 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Catalytic activity

Homogentisate + O2 = 4-maleylacetoacetate.

Cofactor

Iron.

Pathway

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

Subunit structure

Homotrimer Probable.

Involvement in disease

Defects in Hgd are the cause of alkaptonuria (aku). Aku is an autosomal recessive error of metabolism which is characterized by an increase in the level of homogentisic acid.

Sequence similarities

Belongs to the homogentisate dioxygenase family.
