Figure 4: Side-chain interactions between the subunits. a, A
stereo view of the interactions between the three chains around
the C lobe of TnC. b, The hydrophobic residues in the N lobe of
TnC interacting with segment H3(I) of TnI. TnC, TnI and TnT are
coloured pink, cyan and yellow, respectively. The amino acid
residues involved in the interactions are shown in ball and
stick representation. The three Ca^2+ ions bound to sites II,
III and IV are shown by the black spheres.
