Patent abstract

The invention relates to isolated polypeptides with hydantoin recemase activity, that do not suffer from substrate inhibition. Such polypeptides arc for instance isolated polypeptides with at least 87% identity with SEQ ID: NO. 2 or SEQ ED: NO. 4. The invention also relates to nucleic acid sequences encoding these polypeptides. The invention also relates to processes for the racemisation of enantiomerically enriched hydantoin compounds and to processes for the preparation of enantiomarically enriched I)-or I-α amino acids.
