STRUCTURE OF THE BIFUNCTIONAL ISPDF FROM CAMPYLOBACTER JEJUNI

Overview

The bifunctional methylerythritol 4-phosphate cytidylyltransferase, methylerythritol 2,4-cyclodiphosphate synthase (IspDF) is unusual in that, it catalyzes nonconsecutive reactions in the 1-deoxy-D-xylulose, 5-phosphate (DOXP) pathway of isoprenoid precursor biosynthesis. The, crystal structure of IspDF from the bacterial pathogen Campylobacter, jejuni reveals an elongated hexamer with D3 symmetry compatible with the, dimeric 2C-methyl-D-erythritol-4-phosphate cytidylyltransferase and, trimeric 2C-methyl-D-erythritol-2,4-cyclodiphosphate synthase, monofunctional enzymes. Complex formation of IspDF with, 4-diphosphocytidyl-2C-methyl-D-erythritol kinase (IspE), the intervening, enzyme activity in the pathway, has been observed in solution for the, enzymes from C. jejuni and Agrobacterium ...
