Transcription (kt), degradation (kd), and messenger unbinding (ku) rate parameters for the ribosomal protein operon mRNA in the RBM (scaled from those in Earnest et al.1 as discussed in Section 2.2). Each value for the unbinding rates ku was estimated according to Equation S9. The last line gives the harmonic mean over all individual operon rate parameters. These mean values were used to make Figure S10b. Effective rate parameters (kt,eff, kd,eff) are from fitting the simulated messenger distributions with the theory of Peterson et al.24.
