Time evolution
of heavy-atom RMSD in MTMD and TMD simulations.
Three MTMD simulations are the conformational transition from state
I to A via T (I-T-A), the transition from state A to I via T (A-T-I),
and the transition between states I and A (I-A-I), respectively. Conformational
transition from state A to T is also simulated by TMD with different
force constants (1.0, 0.1, and 0.01 kcal/(mol·Å2)). Three crystal structures, 2ITW, 3W32, and 4I20 are the DFG-in active form (A), Src-like
inactive form (T), and DFG-out inactive form (I), respectively. The
RMSD values are calculated with respect to the target structure (2ITW, 3W32, or 4I20).
