Publication number: 20020061560Abstract: The invention includes novel fusion DNA sequences encoding fusion polypeptides which when expressed in a filamentous fungus result in the expression of fusion polypeptides which when secreted result in increased levels of secretion of the desired polypeptide as compared to the expression and secretion of such polypeptides from filamentous fungi transformed with previously used DNA sequences. The fusion DNA sequences comprise from the 5′ terminus four DNA sequences which encode a fusion polypeptide comprising, from the amino to carbonyl-terminus, first, second, third and fourth amino acid sequences. The first DNA sequence encodes a signal peptide functional as a secretory sequence in a first filamentous fungus. The second DNA sequence encodes a secreted polypeptide or portion thereof which is normally secreted from the same filamentous fungus or a second filamentous fungus. The third DNA sequence encodes a cleavable linker polypeptide while the fourth DNA sequence encodes a desired polypeptide.Type: ApplicationFiled: June 1, 2001Publication date: May 23, 2002Applicant: GENENCOR, INC.Inventor: Virgil Bryan Lawlis

Patent number: 5411873Abstract: Processes for producing various heterologous polypeptides which when expressed are either incorrectly processed and hence asssociated with the surface of the host cell or are not processed to mature form. More specifically, processes for the production of heterologous non-human carbonyl hydrolases expressed either in host cells incapable of producing enzymatically active endoprotease or host cells deficient in enzymatically active extracellular endoprotease are disclosed. Such non-human carbonyl hydrolases generally are incapable of autoproteolytic maturation and become associated with the surface of expression hosts which are deficient in enzymatically active extracellular endoprotease. Processes for preparing non-human carbonyl hydrolase and heterologous polypeptides which are expressed as part of a fusion polypeptide are also disclosed, as well as non-human carbonyl hydrolases which are substantially free of the host cell membrane with which they are normally associated.Type: GrantFiled: August 11, 1992Date of Patent: May 2, 1995Assignee: Genencor, Inc.Inventors: Robin M. Adams, Scott D. Power, David B. Powers, James A. Wells, Daniel G. Yansura

Patent number: 5389536Abstract: A substantially enzymatically pure hydrolase is provided which is secreted by and isolatable from Pseudomonas mendocina ATCC 53552. Cloning the gene expressing the hydrolase into a suitable expression vector and culturing, such as fermenting the E. coli strain JM101 harboring a plasmid designated pSNtacII, has been found to provide surprisingly high yields of the hydrolase.Type: GrantFiled: May 23, 1991Date of Patent: February 14, 1995Assignee: Genencor, Inc.Inventors: Gregory L. Gray, Scott D. Power, Ayrookaran J. Poulose

Patent number: 5378621Abstract: This invention provides a method for killing fungal cells without lysing in fermentation processes in order to prepare the fermentation mixture for processing to recover or extract an extracellularly expressed enzyme from the fermentation mixture. A preferred method of this invention comprises adjusting the pH of the fermentation mixture to less than 2.79 using a mineral acid, then adding sufficient acetic acid to the mixture to affect a substantially complete cell kill in mixture. A salt of the acetic acid can be used. The organic acid or salt can be added, then the pH adjusted to the desired level. Other organic acids can be used, in which case the pH of the mixture is adjusted to the pK.sub.a of the selected organic acid before the organic acid is added to the mixture.Type: GrantFiled: May 7, 1993Date of Patent: January 3, 1995Assignee: Genencor, Inc.Inventors: Virgil B. Lawlis, Jr., Henry G. Heinsohn, Enrique F. Baliu
-
Patent number: 5346823Abstract: There are provided methods for making a mutant Bacillus subtilisin having altered oxidative stability, the methods comprising obtaining DNA fragment consisting of a region coding for a Bacillus subtilisin, and introducing a mutation into said DNA fragment such that the mutation is introduced in a region encoding a methionine, tryptophan, cysteine or lysine, sensitive to oxidation, such that upon expression of the mutant subtilisin one or more codon regions encoding for methionine, tryptophan, cysteine or lysine is replaced with an amino acid other than methionine, tryptophan, cysteine or lysine, preferably alanine or serine.Type: GrantFiled: March 24, 1993Date of Patent: September 13, 1994Assignee: Genencor, Inc.Inventors: David A.

Patent number: 5264366Abstract: There are described, normally sporulating mutant Bacillus strain(s) which produce no detectable proteolytic activity during any phase of its growth. The absence of detectable proteolytic activity is due to the deletion of one or more codons specifying the mature subtilisin protease and the mature neutral protease. Also described are methods for producing such normally sporulating, protease deficient Bacillus mutants.Type: GrantFiled: November 25, 1991Date of Patent: November 23, 1993Assignee: Genencor, Inc.Inventors: Eugenio Ferrari, Dennis J.
