| Accepted name: |
propanediol dehydratase |
| Reaction: |
propane-1,2-diol = propanal + H2O |
| Other name(s): |
meso-2,3-butanediol dehydrase; diol dehydratase; DL-1,2-propanediol hydro-lyase; diol dehydrase; adenosylcobalamin-dependent diol dehydratase; propanediol dehydrase; coenzyme B12-dependent diol dehydrase; 1,2-propanediol dehydratase; dioldehydratase; propane-1,2-diol hydro-lyase; RiDD |
| Systematic name: |
propane-1,2-diol hydro-lyase (propanal-forming) |
| Comments: |
Two different forms of the enzyme have been described. One form requires a cobamide cofactor, while the other is a glycyl radical enzyme. The cobamide-dependent enzyme has been shown to also dehydrate ethylene glycol to acetaldehyde. |
