abstract：:Adsorption of phages T4, T5, and BF23 to previously starved Escherichia coli cells triggered the immediate release of respiratory control. A similar stimulation of respiration was induced after T4 ghost attachment, showing that this process was independent of the mechanism of DNA injection. Rather, this change in the ...

The oriTs are made up of a highly conserved core, where DNA is cleaved by the relaxase prior to transfer, and an inverted repeat that differs in size and sequence. We show that in each case ...
