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.

Flavin reductase a class of enzymes. There are a variety of flavin reductases, which bind free flavins and through hydrogen bonding, catalyze the reduction of these molecules to a reduced flavin. Riboflavin, or vitamin B, and flavin mononucleotide are two of the most well known flavins in the body and are used in a variety of processes which include metabolism of fat and ketones and the reduction of methemoglobin in erythrocytes. Flavin reductases are similar and often confused for ferric reductases because of their similar catalytic mechanism and structures.
