Stabilization of the long central helix of troponin C by intrahelical salt bridges between charged amino acid side chains.

The unusual dumbbell shape of troponin C is due to the presence of a long alpha-helix of nine turns that connects the amino- and carboxyl-terminal calcium-binding domains. The center of the long helix appears to be stabilized by several salt bridges. The long helix is also bent about 16 degrees at g...
