Reaction: 2-dehydro-D-gluconate + NADP+ = 2,5-didehydro-D-gluconate + NADPH + H+
Other name(s): 2,5-diketo-D-gluconate reductase (ambiguous)
Systematic name: 2-dehydro-D-gluconate:NADP+ 2-oxidoreductase (2-dehydro-D-gluconate-forming)
Comments: The enzyme is involved in the catabolism of 2,5-didehydrogluconate. cf. EC 1.1.1.346, 2,5-didehydrogluconate reductase (2-dehydro-L-gulonate-forming).
