'''CRYSTAL STRUCTURE OF 4-DIPHOSPHOCYTIDYL-2-C-METHYLERYTHRITOL (CDP-ME) SYNTHASE (YGBP) INVOLVED IN MEVALONATE INDEPENDENT ISOPRENOID BIOSYNTHESIS'''<br />


==Overview==
==CRYSTAL STRUCTURE OF 4-DIPHOSPHOCYTIDYL-2-C-METHYLERYTHRITOL (CDP-ME) SYNTHASE (YGBP) INVOLVED IN MEVALONATE INDEPENDENT ISOPRENOID BIOSYNTHESIS==
The YgbP protein of Escherichia coli encodes the enzyme, 4-diphosphocytidyl-2-C-methylerythritol (CDP-ME) synthetase, a member of, the cytidyltransferase family of enzymes. CDP-ME is an intermediate in the, mevalonate-independent pathway for isoprenoid biosynthesis in a number of, prokaryotic organisms, algae, the plant plastids and the malaria parasite., Because vertebrates synthesize isoprenoid precursors using a mevalonate, pathway, CDP-ME synthetase and other enzymes of the mevalonate-independent, pathway for isoprenoid production represent attractive targets for the, structure-based design of selective antibacterial, herbicidal and, antimalarial drugs. The high-resolution structures of E. coli CDP-ME, synthetase in the apo form and complexed with both CTP-Mg2+ and, CDP-ME-Mg2+ reveal the stereochemical principles underlying both substrate, and product recognition as well as catalysis in CDP-ME synthetase., Moreover, these complexes represent the first experimental structures for, any cytidyltransferase with both substrates and products bound.
