Dissociation of the ampicillin-induced lysis of amino acid-deprived Escherichia coli into two stages.
The ampicillin-induced lysis of amino acid-deprived relA+ Escherichia coli was dissociated into two separate stages. The early stage ("priming") requiring the presence of ampicillin apparently involved the interaction of ampicillin with a target penicillin-binding protein. The later stage ("lysis induction") was ampicillin independent and required only chloramphenicol to relax the RelA-dependent control of peptidoglycan hydrolase activity.
