Malonyl CoA reductase (malonate semialdehyde-forming)

Malonyl CoA reductase (malonate semialdehyde-forming) (EC 1.2.1.75, NADP-dependent malonyl CoA reductase, malonyl CoA reductase (NADP)) is an enzyme with systematic name malonate semialdehyde:NADP oxidoreductase (malonate semialdehyde-forming). This enzyme catalyse the following chemical reaction

malonate semialdehyde + CoA + NADP

\rightleftharpoons

malonyl-CoA + NADPH + H

Requires Mg. Catalyses the reduction of malonyl-CoA to malonate semialdehyde.
