Probing Arginine Side‐Chains and Their Dynamics with Carbon‐Detected NMR Spectroscopy: Application to the 42 kDa Human Histone Deacetylase 8 at High pH

Arginine side-chains play a distinct role because of their high pKa and perpetual positive charge. An NMR method is presented, based on carbon-detected 13Cζ–15Nε correlation spectra, which allows probing the arginine side-chains and their dynamics at neutral-to-high pH. The methodology is demonstrated on human histone deacetylase 8.
