Nicotinamide riboside and nicotinic acid riboside salvage. (A) Nicotinamide riboside salvage in H. influenzae is mediated by the nicotinamide riboside kinase domain and the NMN adenylyltransferase domain of nadR. (B) Nicotinamide riboside and nicotinic acid riboside salvage in S. cerevisiae is mediated by nicotinamide riboside kinase (NRK1)-dependent and nucleoside-splitting pathways.
