== Publication Abstract from PubMed ==

Ribose-5-phosphate isomerase is a ubiquitous intracellular enzyme of bacterial, plant and animal origin that is involved in the pentose phosphate cycle, an essential component of cellular carbohydrate metabolism. Specifically, the enzyme catalyses the reversible conversion of ribose 5-phosphate to ribulose 5-phosphate. The structure of ribose-5-phosphate isomerase from Methanocaldococcus jannaschii has been solved in space group P2(1) to 1.78 A resolution using molecular replacement with one homotetramer in the asymmetric unit and refined to an R factor of 14.8%. The active site in each subunit was occupied by two molecules of propylene glycol in different orientations, one of which corresponds to the location of the phosphate moiety and the other to the location of the furanose ring of the inhibitor.
