Fig. 3. Comparison of the average mechanical properties across the different PRD1-derived particles. In all panels: black bar, PRD1 wt; pink bar, Sus1 procapsid; blue bar, P3-shell; orange bar, vesicle. (a) Stiffness (k); (b) yield force (Fy); (c) yield strain (εy); (d) toughness (T). All panels report the mean values and standard errors of the mean that were derived from the data shown in Fig. 2 (for the vesicle, calculation of toughness is not possible because there is no defined yield point).
