The temperature dependence of protein binding rates. a, The fits of binding progress curves at 15 °C, coloured according to the rates (Supplementary Table S1): orange: 4.4 - 21 min-1; green: 1.0 min-1; aqua: 0.044 - 0.11 min-1; purple: 0.00096 - 0.010 min-1. Post-RI* proteins (S3, S10, and S14) are shown as dashed lines here and in b. b, Arrhenius plots of the observed rates (see Supplementary Fig. S3). The error bars are from the errors in kobs (s.d. from the fits of progress curves). The proteins that bind very rapidly are not shown here or in c. c, Protein binding rates at 15 °C vs. the activation energies (Supplementary Table S1). The errors in Ea are the s.d. from the linear Arrhenius plot fits. Proteins are coloured by 30S domain (magenta: 5′, cyan: central, purple: 3′). Post-RI* proteins have large points.
