Combining Single-Molecule Optical Trapping and Small-Angle X-Ray Scattering Measurements to Compute the Persistence Length of a Protein ER/K α-Helix

A relatively unknown protein structure motif forms stable isolated single α-helices, termed ER/K α-helices, in a wide variety of proteins and has been shown to be essential for the function of some molecular motors. The flexibility of the ER/K α-helix determines whether it behaves as a force transdu...
