Biosynthesis of (S)-(+)-2-amino-4-phenylbutanoic acid (1) was performed by nonenantioselective hydantoinase and L-N-carbamoylase using racemic 5-[2-phenylethyl]-imidazolidine-2,4-dione (rac-2) as a substrate. The compounds involved in this biocatalysis process could be simultaneously resolved by high-performance liquid chromatography using Chirobiotic T column with a mobile phase of EtOH/H2O = 10/90 at pH 4.2-4.5. To our knowledge, this is the first report of the successful production of I by the combination of recombinant hydantoinase and L-N-carbamoylase. (C) 2003 Wiley-Liss, Inc.
