Figure 5.
Conformational sub-states and global fluctuations associated with reactant-product inter-conversion identified using computational simulations and QAA. Top row shows wild-type and bottom row shows the A109G variant. The sub-states are identified using a mixture of Gaussians model (McLachlan and Basford, 1988). Mode 1 (displacement along γ1 axis) corresponds to the large-scale conformational fluctuation (or primary relaxation) associated with the reactant-product sub-states inter-conversion; similarly mode 2 (displacement along γ2 axis) corresponds to the secondary conformational fluctuation.
