Comments
  • FUNCTION: Plays a role in valine and pyrimidine metabolism. Binds fatty acyl-CoA.
  • CATALYTIC ACTIVITY: 2-methyl-3-oxopropanoate + CoA + H2O + NAD+ = propanoyl-CoA + HCO3- + NADH.
  • CATALYTIC ACTIVITY: 3-oxopropanoate + CoA + NAD(P)+ = acetyl-CoA + CO2 + NAD(P)H.
  • SUBUNIT: Homotetramer.
  • SUBCELLULAR LOCATION: Mitochondrion.
  • DISEASE: Defects in ALDH6A1 are the cause of methylmalonate semialdehyde dehydrogenase deficiency (MMSDH deficiency) [MIM:603178]. This is characterized by elevated beta-alanine, 3-hydroxypropionic acid, and both isomers of 3-amino and 3-hydroxyisobutyric acids in urine organic acids.
  • SIMILARITY: Belongs to the aldehyde dehydrogenase family.
