    Abstract: The present invention is directed to a producing a DNA methyltransferase in a recombinant host cell, wherein the DNA methyltransferase methylates DNA resulting in a DNA containing 5-methylcytosine within the recognition sequence GCNGC and wherein the DNA methyltransferase comprises less than (35) amino acid residues between amino acid residue (72) and amino acid residue (106) according to the numbering of SEQ ID NO: 33. Furthermore, the present invention is directed to the use of such DNA methyltransferase for the production of bacterial transformants comprising the steps of (a) introducing into a first bacterial host cell a polynucleotide comprising a polynucleotide sequence encoding the DNA methyltransferase to produce a methylated DNA and (b) transferring the methylated DNA from the first bacterial host cell into a second bacterial host cell, wherein the second bacterial host cell comprises a restriction endonuclease able to degrade the DNA but unable to degrade the methylated DNA.

    Abstract: The present invention relates to a Bacillus licheniformis host cell for production of biological compounds with increased purity. Specifically, the invention relates to a Bacillus licheniformis host with one or more genetic modifications selected from a) a genetic modification causing compared to an unmodified control cell an increased expression of at least one of the genes selected from the group consisting of degQ, degll, degS, degR, and phrG, b) a genetic modification causing compared to an unmodified control cell an increased autophosphorylation activity of the DegS protein, and c) a genetic modification causing compared to an unmodified control cell a reduced phosphatase activity of the DegS protein. The present invention further relates to a method for production of at least one compound of interest with increased purity based on cultivating the bacterial host cell of the present invention.

    Abstract: The present invention relates to a Bacillus host cell for increased production of biological compounds. Specifically, the invention relates to a Bacillus host with genetic modifications that lead to decreased production of components of biofilm and increased levels of phosphorylated De-gll. Said Bacillus host comprises at least one gene expression cassette with a polynucleotide encoding at least one polypeptide of interest, operably linked to a promoter for the production of compounds. The present invention further relates to a method for increased production of at least one polypeptide of interest based on cultivating the bacterial host cell of the present invention.

    Abstract: The present invention is directed to a nucleic acid construct comprising a polynucleotide operably linked to one or more control sequence that directs the expression of the polynucleotide in a host cell, wherein at least one control sequence comprises a promoter sequence of an operon comprising a secA gene or a functional fragment or functional variant thereof and wherein said promoter sequence is heterologous to the polynucleotide. In a further embodiment, the invention is directed to an expression vector and a host cell comprising the nucleic acid construct comprising the promoter sequence described herein and a method of expressing a polynucleotide in a host cell.
