Probing of enzyme reactions by the biocatalyst-induced association or dissociation of redox labels linked to monolayer-functionalized electrodes

摘要

The activities of the enzymes tyrosinase and thrombin are probed by the association of the ferrocene boronic acid label to the enzyme-generated catechol ligand, and by the cleavage of the ligand-redox complex tethered to a peptide, respectively.
