Escherichia coli cells overexpressing the laaA gene have been demonstrated to be applicable to the S-stereoselective hydrolysis of (R,S)-piperazine-2-tert-butylcarboxamide to produce (S)-piperazine-2-carboxylic acid with high optical purity. Enantiomerically pure piperazine-2-carboxylic acid and its tert-butylcarboxamide derivative are important chiral building blocks for some pharmacologically active compounds such as N-methyl-D-aspartate antagonist for glutamate receptor, cardioprotective nucleoside transport blocker and HIV protease inhibitor
