We note that the solution-based FRET distributions in the absence (Figure 4.2D; top panel) and presence (Figure 4.2D; bottom panel) of saturating concentrations of ligand are

For example, when a protein switches between two conformations, such as an open and a closed conformation (Figure 5.1A), an open-liganded state in the

We determined the effect of the length and structure of the linkers, which connect the SBDs to each other and to the translocator domain, on transport by GlnPQ.. We reveal

By using single-molecule FRET we show that the two ATP sites of ABCE1 are always in a dynamic equilibrium between three distinct conformational states: open, intermediate and

When only the energy of

To circumvent this limitation, and to directly relate the SBP conformational changes with the binding of substrate, we developed a single-molecule assay in Chapter 5 to

Dus de NBDs van ABCE1 switchen niet tussen een open en dichte conformatie maar kunnen vele verschillende conformaties aannemen door de asynchrone bewegingen in beide
