US Patent:
6361973, Mar 26, 2002
Filed:
Mar 22, 2000
Appl. No.:
09/534407
Inventors:
Randy M. Berka - Davis CA
Michael W. Rey - Davis CA
Kimberly Brown - Elk Grove CA
Stephen H. Brown - Davis CA
Assignee:
Novozymes Biotech, Inc. - Davis CA
International Classification:
C12P 2102
US Classification:
435 691, 536 241
Abstract:
The present invention relates to methods for producing a polypeptide, comprising: (a) cultivating a fungal host cell in a medium conducive for the production of the polypeptide, wherein the fungal host cell comprises a first nucleic acid sequence encoding the polypeptide operably linked to a second nucleic acid sequence comprising a promoter foreign to the nucleic acid sequence, wherein the promoter comprises a sequence selected from the group consisting of nucleotides 1 to 3949 of SEQ ID NO:1, nucleotides 1 to 938 of SEQ ID NO:2, and nucleotides 1 to 3060 of SEQ ID NO:3, and a subsequence thereof; and mutant, hybrid, and tandem promoters thereof; and (b) isolating the polypeptide from the cultivation medium. The present invention also relates to the isolated promoter sequences and to constructs, vectors, and fungal host cells comprising the promoter sequences operably linked to nucleic acid sequences encoding polypeptides.

Heterologous Polypeptides Expressed In Filamentous Fungi, Processes For Making Same, And Vectors For Making Same

US Patent:
6379928, Apr 30, 2002
Filed:
Dec 10, 1999
Appl. No.:
09/468265
Inventors:
Randy Michael Berka - San Mateo CA
Daniel Cullen - Madison WI
Gregory Lawrence Gray - South San Francisco CA
Kirk James Hayenga - Burlingame CA
Virgil Bryan Lawlis - San Mateo CA
Assignee:
Genencor International, Inc. - Palo Alto CA
International Classification:
C12P 2100
US Classification:
435 711, 435 691, 435 697, 435 698, 435183, 435205, 435223, 435225, 43525411, 4352543, 4352544, 4352546, 4352548
Abstract:
Novel vectors are disclosed for expressing and secreting heterologous polypeptides from filamentous fungi. Such vectors are used in novel processes to express and secrete such heterologous polypeptides. The vectors used for transforming a filamentous fungus to express and secrete a heterologous polypeptide include a DNA sequence encoding a heterologous polypeptide and a DNA sequence encoding a signal sequence which is functional in a secretory system in a given filamentous fungus and which is operably linked to the sequence encoding the heterologous polypeptide. Such signal sequences may be the signal sequence normally associated with the heterologous polypeptides or may be derived from other sources. The vector may also contain DNA sequences encoding a promoter sequence which is functionally recognized by the filamentous fungus and which is operably linked to the DNA sequence encoding the signal sequence. Preferably functional polyadenylation sequences are operably linked to the 3â terminus of the DNA sequence encoding the heterologous polypeptides.
