EXPRESSION SYSTEM COMPRISING ASPERGILLUS NIGER PECTIN LYASE I GENE SEQUENCES

摘要

Novel Expression SystemAbstractRecombinant DNA molecules coding for a pectin lyase expressionsystem and derivatives thereof, such as the structural gene of PLIand corresponding regulatory sequences, e.g. promoter, signal andterminator sequences, and hybrid vectors comprising correspon-ding DNAs, including hybrid vectors with DNA coding for homologousor heterologous polypeptides, hosts, especially filamentous fungi,e.g. Aspergillus hosts, transformed by said vectors, methods for thepreparation of said recombinant DNA molecules and said hosts and theuse of the recombinant DNA molecules for the preparation of newexpression systems. A further objective is the preparation ofpolypeptides by means of said DNAs and said hosts.
