| abstract |
The present invention relates to a method for preparing α-amino-ε-caprolactam, comprising converting lysine to α-amino-ε-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 α-amino-ε-caprolactam is used for preparing c-caprolactam. |
