ENZYME entry: EC 1.2.1.75

Accepted Name
Malonyl CoA reductase (malonate semialdehyde-forming).
Alternative Name(s)
Malonyl CoA reductase (NADP).
NADP-dependent malonyl CoA reductase.
Reaction catalysed
Malonate semialdehyde + CoA + NADP(+) <=> malonyl-CoA + NADPH
Cofactor(s)
Mg(2+).
Comment(s)
  • 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.
