    ABSTRACT: Ribosome biogenesis in eukaryotes is a complex and highly orchestrated process involving more than 200 accessory factors in addition to ribosomal RNAs and ribosomal proteins. Among the many factors involved, Sqt1p has been reported to specifically bind to uL16 and to act as a chaperone. The crystal structure of full-length Sqt1p from the yeast Saccharomyces cerevisiae has been solved at 3.35 Å resolution. A SAD experiment at the Se K edge and an S-SAD experiment on the same selenomethionine-substituted protein crystal allowed unambiguous positioning of the selenomethionine and Cys residues. On the basis of the atomic structure of Sqt1p, the potential residues involved in uL16 interaction were identified and tested.

    ABSTRACT: Drosophila Down syndrome cell adhesion molecule 1 (Dscam1) plays a critical role in neural development. It can potentially form 38 016 isoforms through alternative RNA splicing, and exhibits isoform-specific homophilic interaction through three variable Ig domains (Ig2, Ig3 and Ig7). The diversity and homophilic interaction are essential for its functions. Ig7 has 33 isoforms and is the most variable among the three variable Ig domains. However, only one isoform of Ig7 (isoform 30) has been structurally determined to date. Here, two isoforms of Dscam1 Ig7 (isoforms 5 and 9; Ig7 5 and Ig7 9 ) were produced and crystallized. Diffraction data from Ig7 5 and Ig7 9 crystals were processed to resolutions of 1.95 and 2.37 Å, respectively. Comparison of different Dscam1 Ig7 isoforms will provide insight into the mechanism of its binding specificity.

    ABSTRACT: Acetophenone reductase (APRD) from Geotrichum candidium NBRC 4597 was crystallized by the hanging-drop vapour-diffusion method using PEG 3350 as a precipitant. The crystal belonged to space group P6522, with unit-cell parameters a = b = 104.5, c = 273.7 Å, and diffracted to 2.6 Å resolution. Phasing using the single-wavelength anomalous diffraction method was successful. Model building and crystallographic refinement are in progress.

    ABSTRACT: The arginine repressor (ArgR) is a transcriptional regulator which regulates genes encoding proteins involved in arginine biosynthesis and the arginine catabolic pathway. ArgR from the alkaliphilic bacterium Bacillus halodurans was cloned and overexpressed in Escherichia coli. ArgR (Bh2777) from B. halodurans is composed of 149 amino-acid residues with a molecular mass of 16 836 Da. ArgR was crystallized at 296 K using 1,2-propanediol as a precipitant. Crystals of N-terminally His-tagged ArgR were obtained by the sitting-drop vapour-diffusion method. Dehydrated crystals showed a dramatic improvement in diffraction quality and diffracted to 2.35 Å resolution. The crystals belonged to the cubic space group I23, with unit-cell parameters a = b = c = 104.68 Å. The asymmetric unit contained one monomer of ArgR, which generates a trimer by the threefold axis of the space group, giving a crystal volume per mass (VM) of 2.98 Å(3) Da(-1) and a solvent content of 56.8%.

    ABSTRACT: Two crystal forms of Escherichia coli tryptophanase (tryptophan indole-lyase, Trpase) were obtained under the same crystallization conditions. Both forms belonged to the same space group P 4 3 2 1 2 but had slightly different unit-cell parameters. The holo crystal form, with pyridoxal phosphate (PLP) bound to Lys270 of both polypeptide chains in the asymmetric unit, diffracted to 2.9 Å resolution. The second crystal form diffracted to 3.2 Å resolution. Of the two subunits in the asymmetric unit, one was found in the holo form, while the other appeared to be in the apo form in a wide-open conformation with two sulfate ions bound in the vicinity of the active site. The conformation of all holo subunits is the same in both crystal forms. The structures suggest that Trpase is flexible in the apo form. Its conformation partially closes upon binding of PLP. The closed conformation might correspond to the enzyme in its active state with both cofactor and substrate bound in a similar way as in tyrosine phenol-lyase.
