| β-a. |
an ω-amino acid, β-aminopropionic acid; it is not found in proteins but occurs both free and in several peptides, is a precursor of acetyl coenzyme A and several related compounds, and is an intermediate in the catabolism of uracil and cytosine.

| β-alanine–α-ketoglutarate transaminase |
an enzyme activity that transfers the amino group from β-alanine to α-ketoglutarate, forming glutamate and malonate semialdehyde as a step in the metabolism of β-alanine. The enzyme can also act on γ-aminobutyrate and S-β-aminoisobutyrate; it has been listed as a secondary activity of the enzyme 4-aminobutyrate transaminase but may be a separate enzyme. Deficiency of this enzyme activity causes hyper-β-alaninemia.
