Abstract excerpt
During transcription initiation from galP2, one of the two promoters of the Escherichia coli galactose operon with an initially transcribed sequence of pppAUUUC, RNA polymerase (RNAP) is known to engage nonproductive stuttering synthesis, which is sensitive to the concentration of UTP. This study examines the effect of this nonproductive synthesis on promoter clearance and determines other parameters that might...
