L-2-Aminobutyric acid is synthesized from L-threonine and L-aspartic acid through a ?-transamination reaction. It is an L-alanine analogue with an ethyl side chain. | [Biochem/physiol Actions]
L-α-Aminobutyric acid (AABA) is an isomer of the non-natural amino acid aminobutyric acid with activity in the γ-glutamyl cycle that regulates glutathione biosynthesis. Recently AABA has been studied as a supplement to in vitro maturation medium (NCSU 23 medium) for culture of oozytes and embryos. This product has been qualified for use in cell culture. AABA is also used as a substitute amino acid for alanine in studies on peptide function. | [Synthesis]
The preparation of l-2-aminobutyric acid (l-ABA) is mainly achieved by chemical synthesis or enzymatic conversion. In chemical methods, synthesis of l-ABA has been extensively reported, including ammonolysis of α-halogen acid, reduction reaction, ammoniation hydrolysis reaction and butanone acid reduction. However, the obvious disadvantages of chemical synthesis, such as poor selectivity, harsh reaction conditions, various byproducts, and the difficulty in separation and purification, limited its development. It is reported that l-ABA was synthesized in a transamination reaction from α-ketobutyric acid and l-aspartic acid as substrates using aromatic aminotransferase or produced from α-ketobutyric acid and benzylamine using ω-aminotransferase. l-ABA could also be produced from the reduction of α-keto acids with l-leucine dehydrogenase or glutamate dehydrogenase[1].
