Mitochondrial isoforms of nucleoside diphosphate kinase (NDPK-D or NME4) and creatine kinase (mtCK) are phylogenetically unrelated but share important structural and functional properties. They are both located in the intermembrane/cristae space and use mitochondrially generated ATP to phosphorylate their specific substrates, NDPs or creatine, thus regenerating ADP within the mitochondria. Both enzymes functionally interact with inner membrane adenylate translocator, thus allowing for privileged exchange (channeling) of these metabolites. We will discuss the molecular basis of this metabolite channeling and its functional consequences beyond the simple maintenance of proper nucleotide pools: stimulation of respiration, “energy export”, and regulation of ROS production, permeability transition, and mitochondrial shape.
