Bacteriophage proteins associated with the bacterial membrane after bacteriophage T7 infection.

The majority of the phage-induced proteins made after T7 infection of Escherichia coli are tightly associated with the bacterial membrane. Many of these have been identified. Selective extraction of proteins from these membranes by the detergent Sarkosyl or the chaotropic agent guanidine-hydrochloride indicated that most of these proteins are an integral part of the cytoplasmic membrane and the cell wall. No major changes in the distribution of bacterial proteins in the membrane were observed as a consequence of phage T7 infection.
