Process for producing/secreting a protein by a transformed mould using expression/secretion regulating regions derived from a aspergillus endoxylanase II gene
First Claim
1. A process for production of a protein which comprises culturing cells of a mould transformed with an expression vector comprising a gene encoding said protein operatively linked to at least one regulating region selected from the group consisting ofa) expression and secretion regulating regions of the endoxylanase II gene (exlA gene) of Aspergillus niger var. awamori present on plasmid pAW14B (FIG. 3), which is present in a transformed E. coli strain JM109 deposited at the Centraalbureau voor Schimmelcultures in Baarn, The Netherlands, under N°
- CBS 237.90 on 31 May 1990, andb) functional derivatives of a) having at least one activity selected from the group consisting of expression and secretion regulating activity, wherein said protein is not endoxylanase type II ex Aspergillus niger var. awamori;
and wherein the gene encoding said protein is in frame with any secretion regulating region present.

Abstract
Methods are described for the isolation and characterization of DNA sequences from Aspergillus niger var. awamori which are involved in the expression and secretion of endoxylanase II (exlA) by said Aspergillus mould. A process using these expression and/or secretion regulating regions to direct the production and optionally the secretion of proteins other than endoxylanase II by transformed moulds is provided.
