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.
