N in bacteria

It may be the immediate donor of electrons to a ubiquinone held by a ubiquinone-binding protein designated QP-N. In bacteria seven of these are homologs of the seven NADFl dehydrogenase subunits encoded by mtDNA (Fig. 18-3). A49-kDa subunit of complex I in fhe yeast Yarrowia lipolytica is strikingly similar to the hydrogen reactive subunit of NiFe hydrogenases (Fig.
