Transcription initiation-defective forms of sigma(54) that differ in ability To function with a heteroduplex DNA template.

Journal of bacteriology - 1 Nov 2000

Kelly M T, Ferguson J A, Hoover T R

Abstract excerpt

Transcription by sigma(54)-RNA polymerase holoenzyme requires an activator that catalyzes isomerization of the closed promoter complex to an open complex. We examined mutant forms of Salmonella enterica serovar Typhimurium sigma(54) that were defective in transcription initiation but retained cor...
