Stimuli-responsive, switchable protein assemblies. a) Mg2+-mediated GroELMC nanotube formation and ATP-triggered chemomechanical nanotube scission. b) Thermodynamic model for allosteric assembly of the engineered Cl2 variants controlled by temperature and C-peptide concentration. All the engineered variants populate the same five species: native monomer (N), fold-switched monomer (switch), hexamer (H), dodecamer (H2) and unfolded monomer (U). c) Adenylate kinase (AKe) in open and closed state (left) and structural transition of AKe-based protein amphiphile assembly from 1D nanofilament to 2D rectangular nanosheet upon Ap5A binding.
