The protomer of ClyA, shown in Figure 2 on the right, reveals slight differences between the monomer and protomer. The major conformational changes between the monomer and the protomer are the positions of the N-terminal helix and the beta-tongue. As ClyA oligomerizes and forms a pore, the N-terminal helix swings to the opposite side of the molecule while the beta-tongue changes its conformation and turns into an alpha-helix that interacts with the lipid bilayer. | The protomer of ClyA, shown in Figure 2 on the right, reveals slight differences between the monomer and protomer.

The Chen Lab, in collaboration with the Heuck lab, recently published a paper on [http://www.jbc.org/content/288/43/31042.short, ClyA] assembly. Currently, we are investigating electroosmotic flow and electrophoretic force, the forces that influence polymer translocation through ClyA. | The Chen Lab, in collaboration with the Heuck lab, recently published a paper on [http://www.jbc.org/content/288/43/31042.short, ClyA] assembly.
