the two enzymes were partially purified and separated from each other by various chromatographies . beta-alanine : pyruvic acid transaminase and gamma-aminobutyric acid : alpha-ketoglutaric acid transaminase were induced by the addition of beta-alanine and gamma-aminobutyric acid , respectively , to the growth medium . beta-alanine transaminase showed an optimum ph of 10.0 and optimum temperature of 35 degrees c , and its km values for beta-alanine and pyruvic acid were both 1.1 mm . gamma-aminobutyric acid , epsilon-aminocaproic acid , 2-aminoethylphosphonic acid , and propylamine showed about 30-40 % of the activity of beta-alanine as amino donors , and oxalacetic acid was as good an amino acceptor as pyruvic acid .
