PREPARATION OF ALPHA-AMINO-EPSILON-CAPROLACTAM VIA LYSINE CYCLISATION

摘要

The present invention relates to a method for preparing a-amino-e-caprolactam, comprising converting lysine to a-amino-e-caprolactam, wherein the conversion is catalysed by a biocatalyst. Further, the invention relates to a host cell comprising at least one recombinant vector comprising a nucleic acid sequence encoding a biocatalyst with lysine cyclase activity. Further a method is provided wherein a-amino- e-caprolactam is used for preparing e-caprolactam.
