title: Release of periplasmic enzymes from Escherichia coli by penicillin-ethylenediaminetetraacetate treatment.
abstract: When Escherichia coli cells are converted into spheroplasts by penicillin treatment, none of the periplasmic enzymes is released. However, incubation of the penicillin-induced spheroplasts in a medium containing ethylenediaminetetraacetic acid caused the release of endonuclease I and cyclic phosphodiesterase but not of beta-galactosidase.
