Abstract

The present invention relates to a new D-carbamoylase and the gene sequences which code for this from the organism Arthrobacter crystallopoietes DSM 20117. Plasmids, vectors, microorganisms, particular primers and specific possible uses of the enzymes according to the invention are also mentioned. The invention moreover describes a new process for the discovery of enzymes which can be employed in a process for the preparation of D-amino acids starting from 5′-substituted hydantoins.
