Lysine decarboxylase mutants of Escherichia coli: evidence for two enzyme forms.
Mutants with reduced lysine decarboxylase activity were isolated from an Escherichia coli polyamine auxotroph. These mutants could not produce induced enzyme, showing only a very low level of an apparently constitutive form. Both enzyme forms could be demonstrated in the parental strain.
