Fig. 2. Surface representation of Ca^2+-saturated cTnC
bound to cTnI. Hydrophobic surface area is shown in yellow. The
cTnI regulatory and N-terminal domain helices are shown in
magenta and blue, respectively. cTnI peptides were modeled using
the structures of cTnC-(1-89) bound to cTnI-(147-163) (Protein
Data Bank code 1MXL) and sTnC bound to sTnI-(1-47) (Protein Data
Bank code 1A2X). Views A and B are related by a 90° rotation.
