Abstract excerpt
A set of mutants was generated by targeted deletion of the hsdR loci of two type I restriction modification systems (RMS) identified in Bacillus licheniformis DSM13. Single as well as double knock-outs resulted in strains being readily transformable with plasmids isolated from Bacilli. Introduction of shuttle plasmids isolated from Escherichia coli was routinely possible when the double mutant B. licheniformis...
