Abstract
The structure of the Hfq protein from the bacterium Chromobacterium haemolyticum, which forms crystals in two different spatial groups, has been determined. In both cases, the protein has a specific quaternary hexamer-ring structure. The obtained structure showed a previously undescribed interaction between the C-terminal unstructured part of Hfq and the amino acid residues of the proximal RNA-binding site of the protein. This contact may contribute to the regulation of the binding of RNA molecules to the Hfq protein.
期刊介绍：
Crystallography Reports is a journal that publishes original articles short communications, and reviews on various aspects of crystallography: diffraction and scattering of X-rays, electrons, and neutrons, determination of crystal structure of inorganic and organic substances, including proteins and other biological substances; UV-VIS and IR spectroscopy; growth, imperfect structure and physical properties of crystals; thin films, liquid crystals, nanomaterials, partially disordered systems, and the methods of studies.
