Function
function
Catalyzes the oxidation of malonate semialdehyde (MSA) and methylmalonate semialdehyde (MMSA) into acetyl-CoA and propanoyl-CoA, respectively. Is involved in a myo-inositol catabolic pathway. Bicarbonate, and not CO2, is the end-product of the enzymatic reaction.
Catalytic activity
- 2-methyl-3-oxopropanoate + CoA + H2O + NAD+ = H+ + hydrogencarbonate + NADH + propanoyl-CoA
Pathway
Polyol metabolism; myo-inositol degradation into acetyl-CoA; acetyl-CoA from myo-inositol: step 7/7.
