Protein attributes

Sequence length	535 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (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. 3-oxopropanoate + CoA + NAD(P)+ = acetyl-CoA + CO2 + NAD(P)H.
Subunit structure	Homotetramer.
Subcellular location	Mitochondrion.
Involvement in disease	Defects in ALDH6A1 are the cause of methylmalonate semialdehyde dehydrogenase deficiency (MMSDHD) [MIM:614105]. This is characterized by elevated beta-alanine, 3-hydroxypropionic acid, and both isomers of 3-amino and 3-hydroxyisobutyric acids in urine organic acids. Ref.1
Sequence similarities	Belongs to the aldehyde dehydrogenase family.
