In many instances, its members forms part of complex I that catalyses the transfer of two electrons from NADH to ubiquinone in a reaction that is associated with proton translocation across the membrane, and in this context is a combination predominantly of subunits 2, 4, 5, 14, L, M and N [1]. In many bacterial species these proteins are probable stand-alone transporters not coupled with oxidoreduction [2].
