The phosphoglucose isomerase from Mycobacterium tuberculosis H37Rv was crystallized and diffraction data were collected to 2.8 Å resolution. Phosphoglucose isomerase is a ubiquitous enzyme that catalyzes the isomerization of d-glucopyranose-6-phosphate to d-fructofuranose-6-phosphate. The present investigation reports the expression, purification, crystallization and preliminary crystallographic studies of the phosphoglucose isomerase from Mycobacterium tuberculosis H37Rv, which shares 46% sequence identity with that of its human host. The recombinant protein, which was prepared using an Escherichia coli expression system, was crystallized by the hanging-drop vapour-diffusion method. The crystals diffracted to a resolution of 2.8 Å and belonged to the orthorhombic space group I2{sub 1}2{sub 1}2{sub 1}, with unit-cell parameters a = 109.0, b = 119.8, c = 138.9 Å.
