Notes

This bacterial host strain was derived from E. coli K12 DH10B by deleting the dcm gene encoding cytosine methylation. Additionally, the hsdMS genes encoding methylase and specificity genes (from Staphylococcus aureus clonal complex 1 - MW2) were introduced into the chromosome at neutral locations via recombineering.
The strain can be transformed efficiently with large plasmids due to deoR (nupG) mutation.
Plasmids isolated from this E. coli strain transform S. aureus clonal complex 1 - MW2 at high efficiency.
