Maleylacetoacetate Isomerase

**Semantic type:** Amino Acid, Peptide, or Protein|Enzyme

**Definition:** Maleylacetoacetate isomerase (216 aa, ~24 kDa) is encoded by the human GSTZ1 gene. This protein is involved in catalyzing both the isomerization of maleylacetoacetate forming fumarylacetoacetate and the glutathione-dependent oxygenation of dichloroacetic acid to form glyoxylic acid.
