Metabolite Identification
Common NameMaleylacetoacetic acid
Description4-Maleylacetoacetate is an intermediate in the metabolism of tyrosine. Homogentisate 1,2-dioxygenase is the enzyme, which catalyzes the conversion of homogentisate to 4-maleylacetoacetate. Homogentisate 1,2-dioxygenase or HGD is involved in the catabolism of aromatic rings, more specifically in the break down of the amino acids tyrosine and phenylalanine.

Enzymes

General function:
Involved in catalytic activity
Specific function:
Bifunctional enzyme showing minimal glutathione-conjugating activity with ethacrynic acid and 7-chloro-4-nitrobenz-2-oxa-1,3-diazole and maleylacetoacetate isomerase activity. Has also low glutathione peroxidase activity with T-butyl and cumene hydroperoxides. Is able to catalyze the glutathione dependent oxygenation of dichloroacetic acid to glyoxylic acid.
