Figure 8. Computational method QAA allows identification of multi-scale hierarchy associated with catalysis by enzyme CypA.
(a) Multi-level (2 levels shown) hierarchy of conformational sub-states, each dot is a conformations. Each colored dot represents a single sampled conformation; ellipses indicate sub-states; TS′, TS″, and T indicate transition state area. (b) the free energy profile and conformations in (a) are colored according to reaction coordinate, (c) conformational change between sub-states corresponding to black arrow in (a), and (d) impact of identified motions on CypA’s mechanism.
