Thermal and chemical stability of designed protein assemblies and their components. a) Denaturation of MIC1 in various assembly states (monomer, Cu2+-mediated cage, cage + EDTA, cage + EDTA + Cu2+ (rescued assembly)) induced by GuHCl titration (left) or thermal denaturation (right) monitored by CD spectroscopy at 222 nm. b) Stability of monomeric and self-assembled RIDC3 in THF and iPrOH. c) Thermal and pH-dependent stability of TRAP cages tracked by native PAGE and ns-TEM. d) Thermally induced unfolding of the Ico8 protein cage and the TriEst subunit monitored by changes in molar ellipticity at 222 nm (left) and by light scattering (right).
