  • Publication number: 20100143981
    Abstract: The present invention relates to a whole cell catalytic system for the preparation of an enantiomerically enriched ?-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-?-amino acid from a corresponding hydantoin.

  • Patent number: 6846955
    Abstract: The invention relates to a process for racemising an enantiomer-enriched Schiff base of a primary amino acid amide with a strong base that is chemically reactive towards water. The reaction is conducted in an organic solvent. Preferably a metal alkoxide, a metal alkyl, a metal amide, or a metal hydride, in particular a metal alkoxide is applied as the strong base. As the Schiff base preferably N-benzylidene primary amino acid amide is used, with the primary amino acid amide preferably being derived from an aliphatic primary amino acid amide, for example tertiary-leucine amide. As organic solvent use is preferably made of an aromatic hydrocarbon, a cyclic, aliphatic hydrocarbon or a ether, in particular an aromatic hydrocarbon is applied. The invention may also be applied for the racemisation of an enantiomer-enriched primary amino acid amide.
