The present invention relates to a novel method for the biocatalytic production of unsaturated dicarboxylic acids by cultivating a recombinant microorganism co-expressing a glutaconate CoA-transferase and a 2-hydroxyglutaryl-CoA dehydratase system. The present invention also relates to corresponding recombinant hosts, recombinant vectors, expression cassettes and nucleic acids suitable for preparing such hosts as well as a method of preparing polyamide or polyester copolymers making use of said dicarboxylic acids as obtained by said biocatalytic production method.
