Potentially important : The redox potentials of methanophenazine and CoB‐S‐S‐CoM (see scheme), two cofactors from methanogenic archaea, strongly support the view that methanophenazine plays a central role in the electron transport system of methane‐producing archaea. These redox potentials were measured with a hanging mercury drop electrode as the working electrode and were compared to those of several phenazine ethers.
