An atomic force microscope-based single + molecule method was used to measure the effects of the crowding on + the mechanical stability of a model protein, in this case I-27. As + proteins tend to aggregate, single molecule methods provided a way + to prevent aggregation because of the very low concentration of + proteins in the solution under study. Dextran was used as the + crowding agent with three different molecular weights 6kDa, 10 kDa + and 40 kDa, with concentrations varying from zero to 300 grams per + liter in a pH neutral buffer solution at room temperature. Results + showed that the forces required to unfold biomolecules were + increased when a high concentration of crowder molecules were + added to the buffer solution and that the maximum force required + to unfold a domain was when the crowder size was 10 kDa, which is + comparable to the protein size. Unfolding rates obtained from + Monte Carlo simulations showed that they were also affected in the + presence of crowders. As a consequence, the energy barrier was + also affected. These effects were most notable when the size of + the crowder was 10 kDa, comparable to the size of the protein. On + the other hand, distances to the transition state did not seem to + change when crowders were added to the solution. The effect of + Dextran on the energy barrier was modeled by using established + theories such as Ogston’s and scaled particle theory, neither of + which was completely convincing at describing the results.
