Pyrimidodiazepine synthase
In enzymology, a pyrimidodiazepine synthase is an enzyme that catalyzes the chemical reaction
The 3 substrates of this enzyme are pyrimidodiazepine, glutathione disulfide, and H2O, whereas its two products are 6-pyruvoyltetrahydropterin and glutathione.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with a disulfide as acceptor. The systematic name of this enzyme class is pyrimidodiazepine:glutathione-disulfide oxidoreductase . Other names in common use include PDA synthase, pyrimidodiazepine:oxidized-glutathione oxidoreductase . This enzyme participates in glutathione metabolism.
