ABSTRACT:
Processes are provided for the production of a carbamoylase enzyme which has the capability of converting a D-N-carbamoyl (optionally substituted phenyl) glycine by expressing recombinant DNA encoding a carbamoylase in a homologous host. Also provided are specific recombinant DNA vectors producing high levels of expression of the carbamoylase enzyme and/or hydantoinase enzyme in homologous and heterologous hosts and their use in the production of D-.alpha. amino acids.
