Bacteria. Kanamycin-resistant E. coli. cytR- mutation in OP50 background causes elavated nucleotide levels similar to HT115. A mutation in CytR- was introduced into the OP50 strain by recombineering. Bacterial cells were transformed with pSIM8 plasmid before using as hosts for recombineering. Targeting substrate DNA fragments were amplified by PCR and subcloned into TOPO cloning vector for sequence verification before being electroporated into the host bacterial cells. The primer set used for cloning targeting cytR substrate DNAs (to replace cytR+ with the cytR- mutation identified in HT115 strain): 5'- GCCAGGCGAGGAGTGAGTGTG-3'/5'-AGCGGCGGGCCTTTGACC-3'.
