title: Isolation and characterization of a mutant ColE1 plasmid that allows constitutive colicin E1 synthesis.
abstract: It has been possible to isolate a ColE1 mutant which synthesizes colicin E1 constitutively. This result shows that there must be a gene(s) responsible for the regulation of colicin E1 synthesis.
