Figure 3: Features relevant to the egress of material from the CAV16 135S-like particle during cell entry.
From: Picornavirus uncoating intermediate captured in atomic detail

(a,b) B-factor-coloured cartoon diagrams show that particle expansion greatly increases the relative flexibility around the two opening channels in 135S-like CAV16 in b compared with mature EV71 in a. Residues with B-factors substantially lower than the average are coloured in blue and above the average in red. (c,d) Electrostatic surfaces inside (c) and outside (d) 135S-like CAV16 around the two-fold axis channel contoured at ±3 kT/e.
