The crystal structure of the choline-binding domain of Spr1274 (residues 44–129) has been solved at 2.38 Å resolution with three molecules in the asymmetric unit.
The crystal structure of the Z-isomer of 2,4-diamino-5-[2-(2′-methoxyphenyl)-propenyl]-furo[2,3-d]pyrimidine shows an unusual packing arrangement in which the conserved active site Arg70 forms a salt bridge to the side chain of Glu44 from a symmetry-related molecule.
The crystallization and preliminary diffraction analysis of a β-galactosidase from T. reesei is described. The crystals diffracted to 1.2 Å resolution.
The crystallization is reported of two bacterial tyrosine phosphatases which belong to different enzyme families despite their ability to catalyse identical reactions.
Haemoglobin from Camelus dromedarius provides an interesting case study of adaptation to life in deserts at extremely high temperatures. An ambition to unravel the integrated structural and functional aspects of the casual survival of this animal at high temperatures led the authors to specifically work on this problem. This work reports the preliminary crystallographic study of camel haemoglobin.
In this study, the PaaX-like protein from the hyperthermophilic archaeon Sulfolobus solfataricus P2 was successfully crystallized by the hanging-drop vapour-diffusion method using ammonium sulfate as a precipitant.
Crystallization of the ligand–receptor complex of GDF5 and its type I receptor BRIB requires the presence of the activin type IIB receptor (ActRIIB) for crystal formation, but ActRIIB is not part of the complex found in the asymmetric unit.
The truncated cytosolic domain of the iron transporter FeoB from T. maritima was overexpressed, purified and crystallized. Four native or SeMet crystal forms in a nucleotide-free state or in complex with either GDP or GMPPNP diffracted to resolutions of between 1.5 and 2.1 Å.
The N-terminal domain of nsp2 from avian infectious bronchitis virus has been purified and crystallized. The crystals diffracted to 2.5 Å resolution.
Expression, purification, crystallization, and preliminary X-ray diffraction analysis of the DNA-binding effector domain from an atypical OmpR response regulator homolog, ChxR, encoded by Chlamydia trachomatis are reported.
In order to better elucidate the functions of FlgD in flagellar hook biosynthesis, the three-dimensional structure of FlgD is being determined by X-ray crystallography. Here, the expression, purification, crystallization and preliminary crystallographic analysis of FlgD from P. aeruginosa are reported.

SpaA, one of the major pilins of C. diphtheriae, has been expressed, purified and crystallized and X-ray diffraction data have been collected to 1.6 Å resolution.
The crystallization and preliminary X-ray diffraction analysis of sarcosine dimethylglycine methyltransferase from H. halochoris is reported.
A completely ‘all-locked’ nucleic acid duplex was designed from an E. coli tRNASer microhelix. The helix consists exclusively of LNA building blocks and was crystallized. The crystals diffracted to 1.9 Å resolution.
A preliminary crystallographic analysis at 2.3 Å resolution of protein MJ1225 from M. jannaschii, a putative archaeal homolog of γ-AMPK, is described.
Chlorite dismutase crystals belonged to space group P212121 and diffracted to 3.0 Å resolution at a third-generation synchrotron X-ray source.
Purification and crystallization of LinA allowed the collection of data to 2.25 Å resolution.
FliT is a cytoplasmic flagellar type III substrate-specific export chaperone; it has been expressed, purified and crystallized and the crystals have been characterized by X-ray diffraction.
Recombinant α-(N-acetylaminomethylene)succinic acid amidohydrolase from M. loti MAFF303099 was crystallized and diffraction data were collected at 2.7 Å resolution.
The DEAD-box protein Mss116p was crystallized in a complex with a U10 RNA oligonucleotide and an ATP analog. High glycerol (50%) and l-arginine plus l-glutamate (50 mM each) enabled the concentration of Mss116p to ~10 mg ml−1 for crystallization.
