Sysname
4-aminobutanoate:pyruvate aminotransferase
Reaction(IUBMB)
(1) 4-aminobutanoate + pyruvate = succinate semialdehyde + L-alanine [RN:R10178];
(2) 4-aminobutanoate + glyoxylate = succinate semialdehyde + glycine [RN:R10179]
Reaction(KEGG)
Substrate
4-aminobutanoate [CPD:C00334];
pyruvate [CPD:C00022];
glyoxylate [CPD:C00048]
Product
succinate semialdehyde [CPD:C00232];
L-alanine [CPD:C00041];
glycine [CPD:C00037]
Comment
Requires pyridoxal 5'-phosphate. The enzyme is found in plants that do not have the 2-oxoglutarate dependent enzyme (cf. EC 2.6.1.19). The reaction with pyruvate is reversible while the reaction with glyoxylate only takes place in the forward direction.
