2,5-didehydrogluconate reductase
In enzymology, a 2,5-didehydrogluconate reductase (EC 1.1.1.274) is an enzyme that catalyzes the chemical reaction
- 2-dehydro-D-gluconate + NADP+ 2,5-didehydro-D-gluconate + NADPH + H+

Thus, the two substrates of this enzyme are 2-dehydro-D-gluconate and NADP+, whereas its 3 products are 2,5-didehydro-D-gluconate, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 2-dehydro-D-gluconate:NADP+ 2-oxidoreductase. Other names in common use include 2,5-diketo-D-gluconate reductase, and YqhE reductase.
Structural studies
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 1VP5.
gollark: https://gotify.net/ is one I've seen.
gollark: I'm sure there are some push notification server-ish APIs.
gollark: I mean, if you just let it send POST requests to HTTP endpoints of some sort it could integrate with some things.
gollark: You could probably make it send web notifications somehow, that'd be neat.
gollark: Abigail is hydraz.
