Model fit is presented in Fig. 3A.
Model fit is presented in Fig. 3B to D.
Since polymerase binding is at saturation in experiments, we can only estimate the lower bound of this rate.
For better comparison, the synthesis rate of an mRNA of average length is shown. In the model, transcription is proportional to the actual length of each segment's mRNA using a length-specific synthesis rate of 350 nt · h−1 (in vitro) and 1,630 nt · h−1 (cell culture).
Values for kNPBind and kRdRpBind are given in (molecules · h)−1, and the other constants are given in h−1.
