Peptidoglycan hydrolases in an autolytic mutant of Salmonella typhimurium.


Two peptidoglycan hydrolases were isolated from the autolytic mutant Salmonella typhimurium DA361 (envD). One of them, resistant to penicillin, was found free in the supernatant of partially purified envelopes sedimented by ultracentrifugation, and the other bound to the envelopes proved to be sensitive to the antibiotic. Both were able to hydrolyse in… (More)
