General Information

General Information Comment Organism
malfunction site-directed mutagenesis on Asp281 creates mutants that only show diphosphomevalonate 3-kinase activity, demonstrating that the residue is required in the process of phosphate elimination/decarboxylation, rather than in the preceding phosphorylation step Saccharolobus solfataricus
additional information the conserved aspartate residue, Asp281, shows inability for proton abstraction. Substrate-complex structures of DMD (EC 4.1.1.33) and M3K, overview Saccharolobus solfataricus
physiological function the biosynthesis of isopentenyl diphosphate, a fundamental precursor for isoprenoids, via the mevalonate pathway is completed by diphosphomevalonate decarboxylase. This enzyme catalyzes the formation of isopentenyl diphosphate through the ATP-dependent phosphorylation of the 3-hydroxyl group of (R)-5-diphosphomevalonate followed by decarboxylation coupled with the elimination of the 3-phosphate group. Involvement of a long predicted intermediate, (R)-3-phospho-5-diphosphomevalonate, in the reaction of the enzyme Saccharolobus solfataricus
