In the version of this Article originally published, a pre-factor in the mathematical equations underlying the modelling in the study had been omitted (equations (1) and (2) in the Methods section). The subsequent recalculations have resulted in small changes to the kinetic model parameters in Table 1 and minor modifications to Figs 3a–c, 4 and 5a–e, as well as in Supplementary Figs 6, 7, 13, 15, 16, 18 and Supplementary Table 1a,b. In addition to the missing pre-factor, the terms in square brackets in the ordinary differential equations (ODEs) underlying the dynamic model (equation (1)) were incorrect. All errors have now been corrected in the Article and the Supplementary Information. The conclusions of the work are unaffected by these changes.
