CC   -!- FUNCTION: Catalyzes the oxidation of malonate semialdehyde (MSA) and
CC       methylmalonate semialdehyde (MMSA) into acetyl-CoA and propanoyl-CoA,
CC       respectively. Is involved in a myo-inositol catabolic pathway.
CC       Bicarbonate, and not CO2, is the end-product of the enzymatic reaction.
CC       {ECO:0000255|HAMAP-Rule:MF_01670}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=3-oxopropanoate + CoA + H2O + NAD(+) = acetyl-CoA + H(+) +
