physiological function
an alanine auxotroph (mutated in yfdZ) is isolated from a prototrophic double mutant deficient in AvtA and YfbQ by chemical mutagenesis; Escherichia coli synthesizes L-alanine by means of three aminotransferases, YfbQ, YfdZ, and AvtA; YfbQ contributes to most of the alanine aminotransferase activity in rich medium
physiological function
an alanine auxotroph (mutated in yfdZ) is isolated from a prototrophic double mutant deficient in AvtA and YfbQ, a novel alanine aminotransferase, by chemical mutagenesis; Escherichia coli synthesizes L-alanine by means of three aminotransferases, YfbQ, YfdZ, and AvtA; level of yfdZ expression in minimal medium is higher than in rich medium
