Induction of the autolytic system of Escherichia coli by specific insertion of bacteriophage MS2 lysis protein into the bacterial cell envelope.

abstract：:Recovery from the inhibitory effect of ultraviolet irradiation on the induced synthesis of beta-galactosidase was studied in Escherichia coli B/r. When irradiated cells (520 ergs/mm(2) at 254 nm) were induced and incubated in minimal medium supplemented with Casamino Acids (conditions of catabolite repression), the ab...
