    • To generate an ensemble of polymer configurations with knot size k0 and position p0, we equilibrated the Brownian dynamics simulation in an additional external potential U IO, Kk(k-k0)2/2, Kp(p-p0)2/2 with k, p expressed in terms of the bead coordinates (see main text) and Kk, Kp= 1000. After equilibration, at t, 0, this constraining potential is switched off

    • For each (k0, p0) 450 Brownian dynamics trajectories were simulated for 0 < t < 5. D p, Dk, DkP, vp, and v k (for definition see main text) were determined by fits on 15000 different ensembles of (δk (t, δp t, drawn from the 450 trajectories with replacement in a bootstrapping fashion. Fits were done for t > 1 to allow for microscopic rearrangements. For the same reason, ordinate intercept was allowed when deducing Dk, Dp, and Dkp
