[Effect of recB- and recA-mutations on phage restriction in various modification-restriction plasmid systems of E. coli].
The effect of recB and recA mutations on lambda vir and P1 vir restriction by different restriction-modification plasmid systems of E. coli was studied. It was shown that effect of R1 plasmid coded restriction-modification in E. coli K12 and E. coli B strains and pJA4620 plasmid coded restriction in E. coli K12 is observed only in RecB+ strain. Phenomenon of restriction-modification determined by R124, R245 plasmids does not depend of recB mutation. Effect of recA mutation has not been found in cultures harbouring R1, R245, R124 pJA4620 plasmids.
