Abstract

RNA polymerase was isolated from and from transcription of a DNA fragment containing multiple tandem promoters from followed the pattern of expression observed previously for studies. RNA polymerase was prepared from cultures of that were harvested during the growing phase and during the stationary phase. Promoters that were utilized in only during the stationary phase were utilized only when RNA polymerase was purified from a stationary-phase culture, and not when RNA polymerase was purified from growing cells.
