(S)-3-amino-2-methylpropanoate:2-oxoglutarate aminotransferase
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, (R)-3-amino-2-methylpropionate---pyruvate transaminase, provide a route for interconversion of the enantiomers of 3-amino-2-methylpropanoate.
