This entry represents MECDP (2-C-methyl-D-erythritol 2,4-cyclodiphosphate) synthetase, an enzyme in the non-mevalonate pathway of isoprenoid synthesis, isoprenoids being essential in all organisms. Isoprenoids can also be synthesized through the mevalonate pathway. The non-mevolante route is used by many bacteria and human pathogens, including Mycobacterium tuberculosis and Plasmodium falciparum. This route appears to involve seven enzymes. MECDP synthetase catalyses the intramolecular attack by a phosphate group on a diphosphate, with cytidine monophosphate (CMP) acting as the leaving group to give the cyclic diphosphate product MEDCP. The enzyme is a trimer with three active sites shared between adjacent copies of the protein. The enzyme also has two metal binding sites, the metals playing key roles in catalysis[PubMed12499535].

A number of proteins from eukaryotes and prokaryotes share this common N-terminal signature and appear to be involved in terpenoid biosynthesis. The ygbB protein is a putative enzyme of this type [PubMed10694574].
