Comparative Study of Cyanobacterial and E. coli RNA Polymerases: Misincorporation, Abortive Transcription, and Dependence on Divalent Cations
Figure 5
Abortive and runoff transcriptions by Syn RNAP at the psbA2 promoter in the different concentration of Mg2+. The levels of abortive synthesis of 3 to 11-mer (▲) and the runoff synthesis (●) in 20 min in a single-round are plotted against the concentrations of MgCl2. The ratio of the levels (◊) is also plotted.
