title: Expression of the histidine operon in rho mutants of Escherichia coli.
abstract: Expression of the Escherichia coli histidine operon was measured in four independently isolated sets of strains carrying ten different rho mutations. Rho factor does not act as a major regulatory element of histidine operon attenuation.
