title: Proton pathways in lysozyme.
abstract: Protonic conduction studies are reported for lysozyme as a function of the number of bound water molecules. Lysozyme samples employing proton-injecting palladium black electrodes exhibited conductivities up to eight orders of magnitude greater than those retained between control (copper) electrodes. The results indicate that water involved in multiple hydrogen bond contact with the enzyme together with hydrogen bonded segments of the enzyme structure provide a hydrogen bond network which is capable of supporting considerable protonic conduction.
