Isoleucine 2-epimerase (ILEP) is a novel branched-chain amino acid racemase isolated from Lactobacillus buchneri. In this study, we examined production of free d-branched-chain amino acids such as d-valine, d-leucine, and d-allo-isoleucine, using lactic acid bacteria carrying homologs to ILEP. Twelve

The enantioseparation of standard mixtures composed of protein DL-amino acids was performed by reversed-phase high-performance liquid chromatography of the corresponding diastereomeric isoindolyl derivatives, formed by automated precolumn derivatization with o-phthaldialdehyde (OPA) and a series of N-acyl-L-cysteines(Acyl-Cys). A photodiode-array detector, operating
