A Review on Direct Electrochemistry of Catalase for Electrochemical Sensors [PDF]

Sensors, 2009
Catalase (CAT) is a heme enzyme with a Fe(III/II) prosthetic group at its redox centre. CAT is present in almost all aerobic living organisms, where it catalyzes the disproportionation of H2O2 into oxygen and water without forming free radicals. In order

Electrochemical Characterization of a Complex FeFe Hydrogenase, the Electron-Bifurcating Hnd From Desulfovibrio fructosovorans

Frontiers in Chemistry, 2021
Hnd, an FeFe hydrogenase from Desulfovibrio fructosovorans, is a tetrameric enzyme that can perform flavin-based electron bifurcation. It couples the oxidation of H2 to both the exergonic reduction of NAD+ and the endergonic reduction of a ferredoxin. We
