Are class I (pre-early) proteins of bacteriophage T5 sufficient to induce abortive infection of ColIb+ Escherichia coli?

ABSTRACT

When T5 bacteriophage infect a colicin Ib-containing host, a variety of membrane changes and inhibition of macromolecular synthesis occur. This work shows that all these changes also occur when a mutant of T5 that can only inject 8% of its DNA is used. This indicates that all the information necessary for the abortive infection is present on this 8% (first-step-transfer) DNA.
