Abstract (en)

[origin: WO9907873A1] The invention relates to new microorganisms capable of utilising a N-protected cyclic amino acid derivative, selected from the compounds of the general formula (I), in the form of the racemate or one of its optical isomers, where A together with -N- and -CH is a possibly substituted 4-, 5-, 6-, or 7-membered heterocyclic ring and R<1> is a possibly substituted alkyl, alkoxy, aryl or aryloxy, and/or are capable of hydrolizing a N-protected cyclic amino acid derivative, selected from among the compounds of the general formula (I), as well as to enzyme extracts thereof. The invention also relates to a new method for producing N-protected cyclic L-amino acid derivatives and cyclic D-amino acids by using said microorganisms.
