Protein existenceInferred from homology

General annotation (Comments)

Function

Converts malonate semialdehyde (MSA) and methylmalonate semialdehyde (MMSA) into acetyl-CoA and propanoyl-CoA, respectively By similarity. HAMAP-Rule MF_01670

Catalytic activity

3-oxopropanoate + CoA + NAD(P)+ = acetyl-CoA + CO2 + NAD(P)H. HAMAP-Rule MF_01670

2-methyl-3-oxopropanoate + CoA + H2O + NAD+ = propanoyl-CoA + HCO3- + NADH. HAMAP-Rule MF_01670

Pathway

Polyol metabolism; myo-inositol degradation into acetyl-CoA; acetyl-CoA from myo-inositol: step 7/7. HAMAP-Rule MF_01670

Subunit structure

Homotetramer By similarity.

Sequence similarities

Belongs to the aldehyde dehydrogenase family. IolA subfamily.

Sequence caution

The sequence BAF74776.1 differs from that shown. Reason: Erroneous initiation.
