Enzyme Information

2.5.1.18
Glutathione transferase.
based on mapping to UniProt P78417
RX + glutathione = HX + R-S-glutathione.
-!- A group of enzymes of broad specificity. -!- R may be an aliphatic, aromatic or heterocyclic group; X may be a sulfate, nitrile or halide group. -!- Also catalyzes the addition of aliphatic epoxides and arene oxides to glutathione, the reduction of polyol nitrate by glutathione to polyol and nitrile, certain isomerization reactions and disulfide interchange. -!- Formerly EC 1.8.6.1, EC 2.5.1.12, EC 2.5.1.13, EC 2.5.1.14 and EC 4.4.1.7.
1.20.4.2
Methylarsonate reductase.
based on mapping to UniProt P78417
Methylarsonate + 2 glutathione = methylarsonite + glutathione disulfide + H(2)O.
-!- The product, methylarsonite, is biologically methylated by EC 2.1.1.137 to form cacodylic acid. -!- Formerly EC 1.97.1.7.
1.8.5.1
Glutathione dehydrogenase (ascorbate).
based on mapping to UniProt P78417
2 glutathione + dehydroascorbate = glutathione disulfide + ascorbate.
