Transfection of Escherichia coli and Salmonella typhimurium spheroplasts: host-controlled restriction of infective bacteriophage P22 deoxyribonucleic acid.
Under proper conditions, one infective center was obtained for 3 x 10(8) molecules of P22 phage deoxyribonucleic acid (DNA) when lysozyme-ethylenediaminetetraacetic acid spheroplasts of Escherichia coli were transfected in the presence of 25 mug of protamine sulfate per ml. A 3- to 50-fold B-specific and K-specific E. coli restriction of the incoming P22 DNA was observed. When P22 DNA-infected ...
متن کاملA new Salmonella typhimurium DNA host specificity.
The genetic properties of a new (hspS) host specificity of Salmonella typhimurium were investigated using bacteriophage L. Phage L is a better substrate for s-specific restriction than phage P22. Mutants deficient in s-restriction only were found at the same frequency as mutants deficient in both restriction and modification. Crosses between S. typhimurium Hfr and S. typhimurium For between Esc...

متن کاملTransformation of Salmonella typhimurium by plasmid deoxyribonucleic acid.
A modified transformation procedure that is effective for the introduction of plasmid deoxyribonucleic acid at high frequency into Salmonella typhimurium, as well as into Escherichia coli, is described. Transformed bacteria acquire a circular deoxyribonucleic acid species having the genetic and molecular characteristics of the transforming plasmid.
متن کاملChange in methylation of Salmonella bacteriophage P3 deoxyribonucleic acid with host-controlled modification by Escherichia coli.
Modification of bacteriophage P3 by passage through Escherichia coli K was correlated with a 54% decrease in the content of 6-methylaminopurine in the phage deoxyribonucleic acid.
