'''Crystal structure of D-ribulose 5-phosphate 3-epimerase from Synechocystis to 1.6 angstrom resolution'''<br />


==Overview==
==Crystal structure of D-ribulose 5-phosphate 3-epimerase from Synechocystis to 1.6 angstrom resolution==
The crystal structure of D-ribulose 5-phosphate 3-epimerase (RPE) from the, cyanobacterium Synechocystis was determined by X-ray crystallography to, 1.6 A resolution. The enzyme, which catalyzes the epimerization of, D-ribulose 5-phosphate and D-xylulose 5-phosphate, assembles as a hexamer, of (beta/alpha)(8)-barrels in the crystallographic asymmetric unit. The, active site is highly similar to those of two previously reported RPEs and, provides further evidence for essential catalytic roles for several, active-site residues.
