FunFam 52592: Glutathione S transferase O2, isoform B

There are 3 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Glutathione transferase. [EC: 2.5.1.18]
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.

Glutathione dehydrogenase (ascorbate). [EC: 1.8.5.1]
2 glutathione + dehydroascorbate = glutathione disulfide + ascorbate.
    		 1 Q9VSL4
    Pyrimidodiazepine synthase. [EC: 1.5.4.1]
    2-amino-6-acetyl-3,7,8,9-tetrahydro-3H-pyrimido(4,5-b)[1,4]diazepin-4-one + glutathione disulfide + H(2)O = 6-pyruvoyltetrahydropterin + 2 glutathione.
    • In the reverse direction of reaction, the reduction of 6-pyruvoyl- tetrahydropterin is accompanied by the opening of the 6-membered pyrazine ring and the formation of the 7-membered diazepine ring.
    • The pyrimidodiazepine involved is an acetyldihydro derivative.
    • Involved in the formation of the eye pigment drosopterin in Drosophila melanogaster.
