  • Enzymes and micro organisms with amidase activity which hydrolyze polyamides
    Patent number: 6180388
    Abstract: The present invention relates to a process for the enzymatic hydrolysis of polyamides 6.6 to give adipic acid monomers and hexamethylenediamine monomers. The present invention further relates to an enzyme with amidase activity particularly towards substrates of the oligomer type derived from PA 6.6 and/or PA 6, said enzyme being characterized in that it consists of a peptide sequence corresponding to SEQ ID NO: 1 in the attached sequence listing and/or at least one polypeptide homologous to this sequence. The invention further relates to the DNA coding for said enzyme and to the biological precursors thereof The invention further relates to the microorganisms capable of producing this enzyme and to the hydrolysis process in which this enzyme and/or these microorganisms are applied.
