title: Effects of altered rho gene product on the expression of the Escherichia coli histidine operon.
abstract: An altered rho gene product affects expression of the his operon of Escherichia coli. The effect is greater for the operator proximal portion of the his operon than for the operator distal portion. This "rho effect" appears to be independent of the site of action of hisT-altered histidyl-tRNA.
