A mutation in the RNA polymerase β′ subunit causing depressed ribosomal RNA synthesis in Escherichia coli
Macromolecular synthesis in an Escherichia coli mutant with a temperature-sensitive β′ subunit of RNA polymerase was analysed. At the non-permissive temperature ribosomal RNA synthesis is strongly reduced while m...

Specific stimulation of ribosomal RNA synthesis in E. coli by a protein factor
Ribosomal RNA synthesis in a purified system is stimulated by a crude protein fraction prepared from E. coli. The positive effector which is not associated with RNA polymerase, nor is the sigma factor, increases ...

In vitro transcription of three different ribosomal RNA cistrons of E. coli; heterogeneity of control regions
Ribosomal RNA synthesis from three different rRNA cistrons of E. coli, located on different phage DNAs was compared and found to have the same characteristics as regards chain length, salt and temperature depende...
