The present invention relates to a whole cell catalytic system for the preparation of an enantiomerically enriched α-amino acid from a corresponding hydantoin wherein hydantoinase, L-carbamoylase and hydantoin racemase are coexpressed in a recombinant micro-organism wherein the genes coding for these three enzymes are located on a single replicon. The present invention further relates to the use of such a whole cell catalytic system according in the preparation of an enantiomerically enriched L-α-amino acid from a corresponding hydantoin.
The present invention relates to 5-substituted hydantoins, a process for the preparation of 5-substituted hydantoins and the use of 5-substituted hydantoins in the preparation of enantiomerically enriched α-amino acids. Furthermore, the present invention relates to the preparation of pharmaceutically active products such as perindopril and ramipril using the novel 5-substituted hydantoins.
