Enzymes and microorganisms having amidase activity for hydrolysing polyamides

摘要

The present invention relates to an enzyme with amidase activity, particularly towards substrates of the oligomer type derived from PA 6.6 (formula I) and/or PA 6 (formula II), said enzyme being characterized by a ratiowhich is greater than 2, preferably greater than or equal to 10 and particularly preferably greater than or equal to 50.More precisely, this enzyme consists of the peptide sequence corresponding to the attached sequence SEQ ID NO: 2.The invention further relates to the DNA which codes for this polypeptide SEQ ID NO: 2 and whose sequence corresponds to the attached sequence SEQ ID NO: 1.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.
