Electrocatalytic voltammetry was used for the first time to characterize the europium‐dependent methanol dehydrogenase from Methylacidiphilum fumariolicum SolV. Electrons from methanol oxidation were transported to the electrode using the natural electron acceptor of Eu‐MDH, cytochrome cGJ . Kinetic parameters such as Arrhenius activation energy and pH‐dependence are in line with values obtained by an spectrophotometric assay using phenazine ethosulfate and 2,6‐dichlorophenolindophenol.
