Enzyme Information
| 2.6.1.22 |
(S)-3-amino-2-methylpropionate transaminase.
based on mapping to UniProt P80147
(S)-3-amino-2-methylpropanoate + 2-oxoglutarate = 2-methyl-3- oxopropanoate + L-glutamate.
-!- Also acts on beta-alanine and other omega-amino acids having carbon chains between 2 and 5. -!- The two enantiomers of the 2-methyl-3-oxopropanoate formed by the enzyme interconvert by enolization, so that this enzyme, together with EC 2.6.1.40, provide a route for interconversion of the enantiomers of 3-amino-2-methylpropanoate.

| 2.6.1.19 |
4-aminobutyrate--2-oxoglutarate transaminase.
based on mapping to UniProt P80147
4-aminobutanoate + 2-oxoglutarate = succinate semialdehyde + L-glutamate.
-!- Some preparations also act on beta-alanine, 5-aminopentanoate and (R,S)-3-amino-2-methylpropanoate.
