Enzyme Information
| 1.2.1.75 |
Malonyl CoA reductase (malonate semialdehyde-forming).
based on mapping to UniProt Q96YK1
Malonate semialdehyde + CoA + NADP(+) = malonyl-CoA + NADPH.
-!- Catalyzes the reduction of malonyl-CoA to malonate semialdehyde, a key step in the 3-hydroxypropanoate and the 3-hydroxypropanoate/4-hydroxybutyrate cycles, autotrophic CO(2) fixation pathways found in some green non-sulfur phototrophic bacteria and some thermoacidophilic archaea, respectively. -!- The enzyme from Sulfolobus tokodaii has been purified, and found to contain one RNA molecule per two subunits. -!- The enzyme from Chloroflexus aurantiacus is bifunctional, and also catalyzes the next reaction in the pathway, EC 1.1.1.298.
