Human GTP-specific succinyl-CoA synthetase was produced, purified and crystallized from a solution containing tartrate and CoA. The crystal structure shows tartryl-CoA bound to the enzyme at 1.52 Å resolution.

The structure of a Pseudomonas borneol dehydrogenase was determined at 1.84 Å resolution. Major differences from its homologues in the C-terminal helices and the associated loops may suggest determinants for substrate recognition.

This study presents the crystallization, X-ray diffraction analysis and ligand binding of CuvA (Rv1422) from M. tuberculosis H37Rv and reports that MtCuvA can bind to the cell-wall precursor components uridine diphosphate (UDP)-glucose and UDP-N-acetylglucosamine.

The suitability of a PAS polypeptide as a precipitant to grow protein crystals with high X-ray diffraction quality has been demonstrated, adding this novel class of biosynthetic polymers to the toolset for protein crystallography as an alternative to polyethylene glycol.
