Rv3899c, a hypothetical protein fromMycobacterium tuberculosisthat is conserved within the mycobacteria, is predicted to be secreted and has been found in culture filtrates. Here, Rv3899c has been cloned, expressed inEscherichia coliand purified using standard chromatographic techniques. The hanging-drop vapour-diffusion method with PEG 3350 as a precipitant was used to crystallize the protein. N-terminal sequencing results showed that the amino-acid sequence of the crystallized protein began with GATAG, indicating that it is a fragment containing residues 184–410 of Rv3899c. Rv3899c184–410crystals exhibited the symmetry of space groupP212121, with unit-cell parametersa= 49.88,b= 54.72,c= 75.52 Å, α = β = γ = 90°, and diffracted to a resolution of 1.90 Å.

Fimbrial Adhesins

The attachment of many Gram-negative pathogens to biotic and abiotic surfaces is mediated by fimbrial adhesins, which are assembledviathe classical, alternative and archaic chaperone–usher (CU) pathways. The archaic CU fimbrial adhesins have the widest phylogenetic distribution, yet very little is known about their structure and mechanism of assembly. To elucidate the biogenesis of archaic CU systems, structural analysis of the Csu fimbriae, which are used byAcinetobacter baumanniito form stable biofilms and cause nosocomial infection, was focused on. The major fimbriae subunit CsuA/B complexed with the CsuC chaperone was purified from the periplasm ofEscherichia colicells co-expressing CsuA/B and CsuC, and the complex was crystallized in PEG 3350 solution using the hanging-drop vapour-diffusion method. Selenomethionine-labelled CsuC–CsuA/B complex was purified and crystallized under the same conditions. The crystals diffracted to 2.40 Å resolution and belonged to the hexagonal space groupP6422, with unit-cell parametersa=b= 94.71,c = 187.05 Å, α = β = 90, γ = 120°. Initial phases were derived from a single anomalous diffraction (SAD) experiment using the selenomethionine derivative.

Thioredoxins (Trxs) play important roles in chloroplasts by linking photosynthetic light reactions to a series of plastid functions. They execute their function by regulating the oxidation and reduction of disulfide bonds. ACHT1 (atypical cysteine/histidine-rich Trx1) is a thylakoid-associated thioredoxin-type protein found in theArabidopsis thalianachloroplast. Recombinant ACHT1 protein was overexpressed inEscherichia coli, purified and crystallized by the vapour-diffusion method. The crystal diffracted to 1.7 Å resolution and a complete X-ray data set was collected. Preliminary crystallographic analysis suggested that the crystals belonged to space groupC2221, with unit-cell parametersa = 102.7,b= 100.6,c= 92.8 Å.

D-Threonine aldolase from the green algaChlamydomonas reinhardtii(CrDTA) catalyzes the interconversion of several β-hydroxy-D-amino acids (e.g.D-threonine) and glycine plus the corresponding aldehydes. Recombinant CrDTA was overexpressed inEscherichia coliand purified to homogeneity; it was subsequently crystallized using the hanging-drop vapour-diffusion method at 295 K. Data were collected and processed at 1.85 Å resolution. Analysis of the diffraction pattern showed that the crystal belonged to space groupP1, with unit-cell parametersa= 64.79,b= 74.10,c= 89.94 Å, α = 77.07, β = 69.34, γ = 71.93°. The asymmetric unit contained four molecules of CrDTA. The Matthews coefficient was calculated to be 2.12 Å3 Da−1and the solvent content was 41.9%.

Domain Of Unknown Function

The Os01T0156300 protein fromOryza sativahas been classified into the domain of unknown function (DUF) family DUF1110. DUF1110 family members exist in monocotyledons but not in dicotyledons, and share no sequence identity with proteins for which structures have been reported. In this study, the Os01T0156300 protein was crystallized using the hanging-drop vapour-diffusion method. X-ray diffraction data were collected to 1.84 Å resolution. The crystal belonged to space groupP21, with unit-cell parametersa= 89.9,b= 89.8,c= 107.1 Å, β = 106.6°. The asymmetric unit was estimated to contain 6–11 molecules.
