  ABSTRACT  
 
The crystal structure of the enzyme 4-(cytidine 5'-diphospho)-2-C-methyl-D-erythritol (CDP-ME) kinase from the thermophilic bacterium Thermus thermophilus HB8 has been determined at 1.7-A resolution. This enzyme catalyzes phosphorylation of the 2-hydroxyl group of CDP-ME, the fourth step of the non-mevalonate pathway, which is essential for isoprenoid biosynthesis in several pathogenic microorganisms. Since this pathway is absent in humans, it is an important target for the development of novel antimicrobial compounds. The structure of the enzyme is similar to the structures of mevalonate kinase and homoserine kinase, members of the GHMP superfamily. Lys8 and Asp125 are active site residues in mevalonate kinase that also appear to play a catalytic role in CDP-ME kinase. Both the mevalonate and the non-mevalonate pathways therefore involve closely related kinases with similar mechanisms. Assaying the enzyme showed that CDP-ME kinase will phosphorylate CDP-ME but not 4-(uridine 5'-diphospho)-2-C-methyl-D-erythritol, indicating the substrate pyrimidine moiety is involved in important interactions with the enzyme.

Figure 1.
FIG. 1. Non-mevalonate pathway. The pathway is composed of seven reaction steps and starts with pyruvate and glyceraldehyde-3-phosphate. The enzyme CDP-ME kinase converts CDP-ME into CDP-ME 2-phosphate at the fourth step of the pathway. DXP, 1-deoxy-D-xylulose 5-phosphate; MECDP, 2-C-methyl-D-erythritol 2,4-cyclo-diphosphate; HMBDP, 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate.

FIG. 4. Putative catalytic site of CMK. a, a stereo 2F[o] - F[c] electron density map with a ball-and-stick model around Lys8, Phe^30, and Asp125, which are represented at 1.3 contour level. b, ADP (blue) and ATP (yellow) modeled in anti and syn conformations, respectively. The side chains of Lys8, Asn58, Lys83, Ser95, and Asp125 are represented as ball-and-stick models, and oxygen atoms and nitrogen atoms in these side chains are colored red and blue. The orientation is rotated about 90° around the vertical axis and turned 90° clockwise from that of Fig. 3.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
