Function

[ISPD_ARATH] Enzyme of the plastid non-mevalonate pathway for isoprenoid biosynthesis that catalyzes the formation of 4-diphosphocytidyl-2-C-methyl-D-erythritol from CTP and 2-C-methyl-D-erythritol 4-phosphate (MEP). Is essential for chloroplast development and required for pigments and gibberellins biosynthesis.^[1] ^[2] ^[3]

Publication Abstract from PubMed

The homodimeric 2C-methyl-D-erythritol 4-phosphate cytidylyltransferase contributes to the nonmevalonate pathway of isoprenoid biosynthesis. The crystal structure of the catalytic domain of the recombinant enzyme derived from the plant Arabidopsis thaliana has been solved by molecular replacement and refined to 2.0 A resolution. The structure contains cytidine monophosphate bound in the active site, a ligand that has been acquired from the bacterial expression system, and this observation suggests a mechanism for feedback regulation of enzyme activity. Comparisons with bacterial enzyme structures, in particular the enzyme from Escherichia coli, indicate that whilst individual subunits overlay well, the arrangement of subunits in each functional dimer is different. That distinct quaternary structures are available, in conjunction with the observation that the protein structure contains localized areas of disorder, suggests that conformational flexibility may contribute to the function of this enzyme.

The crystal structure of a plant 2C-methyl-D-erythritol 4-phosphate cytidylyltransferase exhibits a distinct quaternary structure compared to bacterial homologues and a possible role in feedback regulation for cytidine monophosphate.,Gabrielsen M, Kaiser J, Rohdich F, Eisenreich W, Laupitz R, Bacher A, Bond CS, Hunter WN FEBS J. 2006 Mar;273(5):1065-73. PMID:16478479^[4]
