CRYSTAL STRUCTURE OF HUMAN NICOTINAMIDE MONONUCLEOTIDE ADENYLYLTRANSFERASE IN COMPLEX WITH NMN
Overview
The final step in the biosynthesis of nicotinamide-adenine dinucleotide, a, major coenzyme in cellular redox reactions and involved in intracellular, signaling, is catalyzed by the enzyme nicotinamide mononucleotide, adenylyltransferase (NMNAT). The X-ray structure of human NMNAT in complex, with nicotinamide mononucleotide was solved by the single-wavelength, anomalous dispersion method at a resolution of 2.9 A. Human NMNAT is a, symmetric hexamer whose subunit is formed by a large six-stranded parallel, beta-sheet with helices on both sides. Human NMNAT displays a different, oligomerization compared to the archaeal enzyme. The protein-nicotinamide, mononucleotide interaction pattern provides insight into ligand binding in, the human enzyme.
