L-alanine	alanine racemase can discriminate effectively between L-alanine and L-2-aminobutyric acid, and selectively and reversibly catalyzes L-alanine to D-alanine transformation Therefore, the enzyme shows ability of eliminating L-Ala from the reaction mixtures of L-2-aminobutyric acid biosynthesis, method optimization and evaluation in a coupled reaction with D-amino acid oxidase converting D-alanine to pyruvate stereoselectively, overview	Bacillus subtilis	D-alanine	-	r
