EcoR124 and EcoR124/3 are type I DNA restriction and modification systems. The EcoR124/3 system arose from the EcoR124 system some 15 years ago and at the electron microscopic DNA heteroduplex level… Expand

The hsdR, hsdM and hsdS genes coding for R.EcoK restriction endonuclease, both with and without a temperature sensitive mutation (ts-1) in the hsdS gene, were cloned in pBR322 plasmid and introduced… Expand
Host specificity of DNA in Haemophilus influenzae: the restriction and modification systems in strains Rb and Rf.
Summary: Haemophilus influenzae Rf possesses two distinct host specificity systems F1 and F2 each of which is able to restrict and modify Haemophilus phage HP1c1, while strain Rb possesses only one… Expand

The restriction of phage T3 by certain strains of Escherichia coli
Restriction and modification of bacteriophages by R+ strains of Escherichia coli K12.
Complementation analysis of temperature-sensitive host specificity mutations in Escherichia coli.
Abstract A selection procedure was devised for the isolation of temperature-sensitive mutants of Escherichia coli Kl2 unable to restrict foreign DNA. Many of the non-restricting mutants isolated also… Expand
Genetics of host-controlled restriction and modification in Escherichia coli.
The sites of mutations affecting host-controlled modification (HCM) have been mapped in E. coli K and E. coli B by conjugation and transduction experiments between mutants. These mutations all map… Expand
