    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 is concerned with materials and methods for nucleic acid and/or protein analysis, including materials and methods for creating and/or analysing mutant libraries. The invention in particular relates to materials and methods for correlating a property of mutants of a target nucleic acid to the respective sequences of the mutants. The invention is particularly useful for analysing saturation mutagenesis libraries and the analysis of sensitivities to chemical or physical conditions, for example temperature stability and solvent stability, and for the analysis of production properties, for example yield or cellular localisation.
