Abstract
A process is described for the production of D-&agr;-amino acids by the stereospecific conversion of racemic mixtures of 5-substituted hydantoins using a microorganism transformed with a plasmid which expresses an enzymatic system which converts the hydantoins into the corresponding D-&agr;-amino acids without the requirement for inducers. Also described is a plasmid containing genes encoding the enzymatic system, and a microorganism transformed with the plasmid.
