Enzyme Information
| 1.1.1.346 |
2,5-didehydrogluconate reductase (2-dehydro-L-gulonate-forming).
based on mapping to UniProt P06632
2-dehydro-L-gulonate + NADP(+) = 2,5-didehydro-D-gluconate + NADPH.
-!- The enzyme is involved in ketogluconate metabolism, and catalyzes the reaction in vivo in the reverse direction to that shown. -!- It is used in the commercial microbial production of ascorbate. -!- cf. EC 1.1.1.274.
