DE   2,5-didehydrogluconate reductase (2-dehydro-L-gulonate-forming).
AN   2,5-diketo-D-gluconate-reductase.
CA   2-dehydro-L-idonate + NADP(+) = 2,5-didehydro-D-gluconate + NADPH + H(+).
CC   -!- The enzyme is involved in ketogluconate metabolism, and catalyzes the
CC       reaction in vivo in the reverse direction to that shown.
CC   -!- It is used in the commercial microbial production of ascorbate. cf.
CC       EC 1.1.1.274.
