Structure of the D-Ribose-5-Phosphate Isomerase from Pyrococcus horikoshii

A hyperthermostable D-ribose-5-phosphate isomerase from Pyrococcus horikoshii characterization and three-dimensional structure.

0.1M HEPES-Na buffer, 0.8M Na-phosphate, 0.8M K-phosphate, pH 7.5, VAPOR DIFFUSION, HANGING DROP, temperature 294K

1LK7 contains the same protein complexed with phospho-erythronic acid

The structure was refined also with REFMAC

D-Ribose-5-Phosphate Isomerase(E.C.5.3.1.6)

The biological assembly is the tetramer in the asymetric unit
