摘要

Recombinant DNA molecules coding for a pectin lyase expression system and derivatives thereof, such as the structural gene of PLI and corresponding regulatory sequences, e.g. promoter, signal and terminator sequences, and hybrid vectors comprising corresponding DNAs, including hybrid vectors with DNA coding for homologous or heterologous polypeptides, hosts, especially filamentous fungi, e.g. Aspergillus hosts, transformed by said vectors, methods for the preparation of said recombinant DNA molecules and said hosts and the use of the recombinant DNA molecules for the preparation of new expression systems. A further objective is the preparation of polypeptides by means of said DNAs and said hosts.
