Figure 1.

(A) Ribbon diagram of troponin and its different subunits. Blue represents TnC (1–161), red represents TnI (1–171) and green represents TnT (212–298). Catalytic and structural Ca²⁺ are shown as gray spheres, and the inhibitory and the switch peptide of TnI are indicated. (B) Snapshot of troponin MD simulation, showing troponin surface rendering in a solvent box. Blue represents TnC (1–161), red represents TnI (1–171) and green represents TnT (212–298).
