Official Name
Methylmalonate-semialdehyde dehydrogenase (acylating).
Alternative Name(s)
MMSA dehydrogenase.
MSDH.
Reaction catalysed
2-methyl-3-oxopropanoate + CoA + H(2)O + NAD(+) <=> propanoyl-CoA + HCO(3)(-) + NADH
Comment(s)
  • Also converts 3-oxopropanoate into acetyl-CoA.
  • The reaction occurs in two steps with the decarboxylation process preceding CoA-binding.
  • Bicarbonate rather than CO(2) is released as a final product.
