| Accepted name: |
2-dehydro-3-deoxy-L-rhamnonate dehydrogenase (NAD+) |
| Reaction: |
2-dehydro-3-deoxy-L-rhamnonate + NAD+ = 2,4-didehydro-3-deoxy-L-rhamnonate + NADH + H+ |

| Other name(s): |
2-keto-3-deoxy-L-rhamnonate dehydrogenase |
| Systematic name: |
2-dehydro-3-deoxy-L-rhamnonate:NAD+ 4-oxidoreductase |
| Comments: |
The enzyme, characterized from the bacteria Sphingomonas sp. SKA58 and Sulfobacillus thermosulfidooxidans, is involved in the non-phosphorylative degradation pathway for L-rhamnose. It does not show any detectable activity with NADP+ or with other aldoses. |
