Abstract:
The present invention relates to Bacillus licheniformis host cells producing heterologous polypeptide of interest, wherein at least one gene in the Ian gene cluster inactivated and methods for producing the polypeptide of interest by cultivating said cells.
Abstract:
Methods of constructing a cell comprising in its chromosome one or more copies of an open reading frame (ORF) or operon encoding at least one polypeptide of interest, each copy being under the transcriptional control of a heterologous promoter using a site specific recombinase and in vivo integration by recombination; means for carrying out the methods, resulting cells, and methods for producing a polypeptide of interest using the resulting cells.
Abstract:
The present invention relates to nucleic acid constructs comprising a first polynucleotide encoding a signal peptide from a bacterial DUF3298 domain-containing polypeptide and a second polynucleotide encoding a polypeptide having cutinase activity; expression vectors and host cells comprising said nucleic acid constructs; and methods for producing polypeptides having cutinase activity.
Abstract:
The present invention provides methods for directly transferring a recombinant polynucleotide of interest from the chromosome of a prokaryotic donor cell to the chromosome of a prokaryotic recipient cell of another species, wherein the polynucleotide of interest comprises at least one coding sequence of interest, preferably one gene of interest and a selectable marker, wherein said polynucleotide of interest in the chromosome of the donor cell is flanked on each side by a polynucleotide region derived from the chromosome of the recipient cell, and wherein the flanking polynucleotide regions are of sufficient size and sequence identity to allow double homologous recombination with the corresponding regions in the chromosome of the recipient cell.
Abstract:
A progeny cell derived from a parent cell, wherein the progeny cell comprises at least one gene encoding MrgA protein or a functional homologue thereof and/or a DNA segment operably linked with the encoding gene, wherein said gene and/or DNA segment is manipulated with respect to the parent cell; the progeny cell comprises two or more copies of a gene encoding MrgA protein or a functional homologue thereof; or the progeny cell is mutated with respect to the parent cell; whereby the progeny cell produces greater amounts of MrgA protein or a functional homologue thereof than the parent cell.
Abstract:
The present invention relates to means and methods for optimizing expression of a heterologous polypeptide of interest in Gram-positive host cells by co-expression with a foldase that is cognate to the heterologous polypeptide of interest.
Abstract:
The present invention relates to RNAse-inactivated Gram positive host cells producing double-stranded RNA (dsRNA) molecules suitable for various applications, including, RNA-interference or gene silencing in one or more target microorganism or organism, such as, plants, insects, nematodes and/or higher animals. The invention also relates to methods of producing dsRNA in the RNAse-inactivated Gram positive host cells and the resulting compositions.
Abstract:
A bacterial host cell comprising at least two copies of an amplification unit in its genome, said amplification unit comprising: i) at least one copy of a gene of interest, and ii) an expressible conditionally essential gene, wherein the conditionally essential gene is either promoterless or transcribed from a heterologous promoter having an activity substantially lower than the endogenous promoter of said conditionally essential gene, and wherein the conditionally essential gene if not functional would render the cell auxotrophic for at least one specific substance or unable to utilize one or more specific sole carbon source; methods for producing a protein using the cell of the invention, and methods for constructing the cell of the invention.
