1.1.1.373 |
| Accepted name: |
sulfolactaldehyde 3-reductase |
| Reaction: |
2,3-dihydroxypropane-1-sulfonate + NAD+ = 2-hydroxy-3-oxopropane-1-sulfonate + NADH + H+ |
| Glossary: |
2-hydroxy-3-oxopropane-1-sulfonate = sulfolactaldehyde |
| Other name(s): |
yihU (gene name) |
| Systematic name: |
2,3-dihydroxypropane-1-sulfonate:NAD+ 3-oxidoreductase |
| Comments: |
The enzyme, characterized from the bacterium Escherichia coli, is involved in the degradation pathway of sulfoquinovose, the polar headgroup of sulfolipids found in the photosynthetic membranes of all higher plants, mosses, ferns, algae, and most photosynthetic bacteria, as well as the surface layer of some archaea. |
