Single-Residue Protection Factor: A simple weblet

This converts footprinting rates to structure-based protection factors

Select Residue Name:

rate constant

protection factor

Note 1: all PF values are at a relative scale, using Proline as a reference state.

Note 2: Cross-residue comparison is valid if experimental conditions are identical.
