a) The eight lowest energy solution NMR structures of cChimera (cTnI switch region shown in red). b) The x-ray structure cNTnC-cTnI derived from the cardiac troponin complex (1J1E.pdb, grey) was aligned by secondary structural elements (residues 3–85) to cChimera (cNTnC region: blue, cyan, green, and yellow spectrum, cTnI inhibitory region linker: orange, cTnI switch region: red). c) Residue Val146 of cTnI (red) forms contacts with Pro52, Glu56 and Met60 (green) of cNTnC, shown in sticks.
