Expression of the histidine operon in rho mutants of Escherichia coli


, : Expression of the histidine operon in rho mutants of Escherichia coli. Journal of Bacteriology 135(2): 721-725

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.
