CC -!- FUNCTION: Probable bifunctional enzyme showing minimal glutathione-
CC conjugating activity with ethacrynic acid and 7-chloro-4-nitrobenz-2-
CC oxa-1, 3-diazole and maleylacetoacetate isomerase activity. Has also
CC low glutathione peroxidase activity with t-butyl and cumene
CC hydroperoxides (By similarity). Is able to catalyze the glutathione
CC dependent oxygenation of dichloroacetic acid to glyoxylic acid.
CC {ECO:0000250, ECO:0000269|PubMed:9531472}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=4-maleylacetoacetate = 4-fumarylacetoacetate;
CC Xref=Rhea:RHEA:14817, ChEBI:CHEBI:17105, ChEBI:CHEBI:18034;
CC EC=5.2.1.2; Evidence={ECO:0000269|PubMed:9531472};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=glutathione + RX = a halide anion + an S-substituted
CC glutathione + H(+); Xref=Rhea:RHEA:16437, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16042, ChEBI:CHEBI:17792, ChEBI:CHEBI:57925,
CC ChEBI:CHEBI:90779; EC=2.5.1.18;
CC Evidence={ECO:0000269|PubMed:9531472};
CC -!- COFACTOR:
CC Name=glutathione; Xref=ChEBI:CHEBI:57925; Evidence={ECO:0000250};
CC Note=Glutathione is required for the MAAI activity. {ECO:0000250};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=71.4 uM for dichloroacetic acid {ECO:0000269|PubMed:9531472};
CC KM=59.0 uM for glutathione {ECO:0000269|PubMed:9531472};
CC Vmax=1334 nmol/min/mg enzyme {ECO:0000269|PubMed:9531472};
CC -!- PATHWAY: Amino-acid degradation; L-phenylalanine degradation;
CC acetoacetate and fumarate from L-phenylalanine: step 5/6.
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:9531472}.
CC -!- PTM: The N-terminus is blocked.
CC -!- SIMILARITY: Belongs to the GST superfamily. Zeta family. {ECO:0000305}.
