Publication Abstract from PubMed
The X-ray crystal structure of the 2C-methyl-D-erythritol 2,4-cyclodiphosphate synthase (MCS) from Arabidopsis thaliana has been solved at 2.3 A resolution in complex with a cytidine-5-monophosphate (CMP) molecule. This is the first structure determined of an MCS enzyme from a plant. Major differences between the A. thaliana and bacterial MCS structures are found in the large molecular cavity that forms between subunits and involve residues that are highly conserved among plants. In some bacterial enzymes, the corresponding cavity has been shown to be an isoprenoid diphosphate-like binding pocket, with a proposed feedback-regulatory role. Instead, in the structure from A. thaliana the cavity is unsuited for binding a diphosphate moiety, which suggests a different regulatory mechanism of MCS enzymes between bacteria and plants.
