Catalysis of Hydrogen Evolution by Polylysine, Polyarginine and Polyhistidine at Mercury Electrodes

Original language description

Protein catalyzed hydrogen evolution reaction at mercury-containing electrodes controlled by constant-current chronopotentiometric stripping (CPS) is representing a new tool useful in protein research. The resulting CPS peak H is sensitive to changes inthe protein structure and its amino acid composition. Besides CPS, cyclic voltammetry appears to be useful for study of poly(amino acids) as an intermediate model system between peptides and macromolecular proteins. Here we show that similarly as arginine in polyarginine and lysine in polylysine also histidine residues in polyhistidine contribute to the catalysis of hydrogen evolution under the given conditions. Peak potentials of individual poly(amino acids) are different and depend on the type of amino acid residues.
