Contraction protein thermally driven

Figure 5.5. Transitions, plotted as independent variable versus dependent variable, showing a response limited to a partieular range of independent variable. (A) Representation of the thermally driven contraction for an elastic-contractile model protein, such as the cross-linked poly(GVGVP), plotted as the percent contraction (dependent variable) versus temperature (independent variable). The plot shows a poorly responsive range below the onset of the transition, the temperature interval of the inverse temperature transition for hydrophobic association, and another poorly responsive region above the tem-...

Figure 5.14. Sheet of elastic model protein of y-irradiation cross-linked (GVGVP)25i as demonstrated in Figure 5.13 directly usable in thermally driven contraction and in chemically driven contraction.

Axiom S At constant temperature, an energy input that changes the temperature interval for thermally driven hydrophobic association in a model protein can drive contraction, that is, oillike folding and assembly, with the performance of mechanical work in other words, the energy input moves the system through the transition zone for contraction due to hydrophobic association. 

To this point thermal and chemical energies have driven contraction without a change in amino acid composition of the basic model protein. An elastic sequence from the mammalian elastic fiber has been used as naturally found, albeit a sequence separate from and syn-...
