Crystal structure of ?-d,l-allose.

ABSTRACT: The title compound, C6H12O6, a C-3 position epimer of glucose, was crystallized from an equimolar mixture of d- and l-allose. It was confirmed that d-allose (l-allose) formed ?-pyran-ose with a (4) C 1 ((1) C 4) conformation in the crystal. In the crystal, molecules are linked by O-H?O hydrogen bond, forming a three-dimensional framework. The cell volume of the racemic ?-d,l-allose is 739.36?(3)?Å(3), which is about 10?Å(3) smaller than that of chiral ?-d-allose [V = 751.0?(2)?Å(3)].

Crystal structure of β-d,l-psicose.

Project description:The title compound, C6H12O6, a C-3 position epimer of fructose, was crystallized from an aqueous solution of equimolar mixture of d- and l-psicose (1,3,4,5,6-penta-hydroxy-hexan-2-one, ribo-2-hexulose, allulose), and it was confirmed that d-psicose (or l-psicose) formed β-pyran-ose with a (2) C 5 (or (5) C 2) conformation. In the crystal, an O-H⋯O hydrogen bond between the hy-droxy groups at the C-3 and C-2 positions connects homochiral mol-ecules into a column along the b axis. The columns are linked by other O-H⋯O hydrogen bonds between d- and l-psicose mol-ecules, forming a three-dimensional network. An intra-molecular O-H⋯O hydrogen bond is also observed. The cell volume of racemic β-d,l-psicose [763.21 (6) Å(3)] is almost the same as that of chiral β-d-psicose [753.06 Å(3)].

Crystal structure of β-d,l-fructose.

Project description:The title compound, C6H12O6, was crystallized from an aqueous solution of equimolar mixture of d- and l-fructose (1,3,4,5,6-penta-hydroxy-hexan-2-one, arabino-hexulose or levu-lose), and it was confirmed that d-fructose (or l-fructose) formed β-pyran-ose with a (2) C 5 (or (5) C 2) conformation. In the crystal, two O-H⋯O hydrogen bonds between the hy-droxy groups at the C-1 and C-3 positions, and at the C-4 and C-5 positions connect homochiral mol-ecules into a column along the a axis. The columns are linked by other O-H⋯O hydrogen bonds between d- and l-fructose mol-ecules, forming a three-dimensional network.

Crystal structure of inhibitor of κB kinase β.

Project description:Inhibitor of κB (IκB) kinase (IKK) phosphorylates IκB proteins, leading to their degradation and the liberation of nuclear factor κB for gene transcription. Here we report the crystal structure of IKKβ in complex with an inhibitor, at a resolution of 3.6 Å. The structure reveals a trimodular architecture comprising the kinase domain, a ubiquitin-like domain (ULD) and an elongated, α-helical scaffold/dimerization domain (SDD). Unexpectedly, the predicted leucine zipper and helix-loop-helix motifs do not form these structures but are part of the SDD. The ULD and SDD mediate a critical interaction with IκBα that restricts substrate specificity, and the ULD is also required for catalytic activity. The SDD mediates IKKβ dimerization, but dimerization per se is not important for maintaining IKKβ activity and instead is required for IKKβ activation. Other IKK family members, IKKα, TBK1 and IKK-i, may have a similar trimodular architecture and function.

Crystal structure of a full-length beta-catenin.

Project description:beta-catenin plays essential roles in cell adhesion and Wnt signaling, while deregulation of beta-catenin is associated with multiple diseases including cancers. Here, we report the crystal structures of full-length zebrafish beta-catenin and a human beta-catenin fragment that contains both the armadillo repeat and the C-terminal domains. Our structures reveal that the N-terminal region of the C-terminal domain, a key component of the C-terminal transactivation domain, forms a long alpha helix that packs on the C-terminal end of the armadillo repeat domain, and thus forms part of the beta-catenin superhelical core. The existence of this helix redefines our view of interactions of beta-catenin with some of its critical partners, including ICAT and Chibby, which may form extensive interactions with this C-terminal domain alpha helix. Our crystallographic and NMR studies also suggest that the unstructured N-terminal and C-terminal tails interact with the ordered armadillo repeat domain in a dynamic and variable manner.

Crystal structure of a dimeric β-diketiminate magnesium complex.

Project description:The solid-state structure of a dimeric β-diketiminate magnesium(II) complex is discussed. The compound, di-μ-iodido-bis-[(-{4-amino-1,5-bis-[2,6-bis-(propan-2-yl)phen-yl]pent-3-en-2-yl-idene}aza-nido-κ2N,N')magnesium(II)] toluene sesquisolvate, [Mg2(C29H41N2)2I2]·1.5C7H8, crystallizes as two independent mol-ecules, each with 2/m crystallographic site symmetry, located at Wyckoff sites 2c and 2d. These have symmetry-equivalent magnesium atoms bridged by μ-iodide ligands with very similar Mg-I distances. The two Mg atoms are located slightly below (∼0.5 Å) the least-squares plane defined by N-C-C-N atoms in the ligand scaffold, and are approximately tetra-hedrally coordinated. One and one-half toluene solvent mol-ecules are disordered with respect to mirror-site symmetry at Wyckoff sites 4i and 2a, respectively. In the former case, two toluene mol-ecules inter-act in an off-center parallel stacking arrangement; the shortest C to C' (π-π) distance of 3.72 (1) Å was measured for this inter-action.

Crystal structure of β-barrel assembly machinery BamCD protein complex.

Project description:The β-barrel assembly machinery (BAM) complex of Escherichia coli is a multiprotein machine that catalyzes the essential process of assembling outer membrane proteins. The BAM complex consists of five proteins: one membrane protein, BamA, and four lipoproteins, BamB, BamC, BamD, and BamE. Here, we report the first crystal structure of a Bam lipoprotein complex: the essential lipoprotein BamD in complex with the N-terminal half of BamC (BamC(UN) (Asp(28)-Ala(217)), a 73-residue-long unstructured region followed by the N-terminal domain). The BamCD complex is stabilized predominantly by various hydrogen bonds and salt bridges formed between BamD and the N-terminal unstructured region of BamC. Sequence and molecular surface analyses revealed that many of the conserved residues in both proteins are found at the BamC-BamD interface. A series of truncation mutagenesis and analytical gel filtration chromatography experiments confirmed that the unstructured region of BamC is essential for stabilizing the BamCD complex structure. The unstructured N terminus of BamC interacts with the proposed substrate-binding pocket of BamD, suggesting that this region of BamC may play a regulatory role in outer membrane protein biogenesis.

Crystal structure of endo-1,4-β-glucanase from Eisenia fetida.

Project description:The saccharification process is essential for bioethanol production from woody biomass including celluloses. Cold-adapted cellulase, which has sufficient activity at low temperature (<293 K), is capable of reducing heating costs during the saccharification process and is suitable for simultaneous saccharification and fermentation. Endo-1,4-β-glucanase from the earthworm Eisenia fetida (EF-EG2) belonging to glycoside hydrolase family 9 has been shown to have the highest activity at 313 K, and also retained a comparatively high activity at 283 K. The recombinant EF-EG2 was purified expressed in Pichia pastoris, and then grew needle-shaped crystals with dimensions of 0.02 × 0.02 × 1 mm. The crystals belonged to the space group P3221 with unit-cell parameters of a = b = 136 Å, c = 55.0 Å. The final model of EF-EG2, including 435 residues, two ions, seven crystallization reagents and 696 waters, was refined to a crystallographic R-factor of 14.7% (free R-factor of 16.8%) to 1.5 Å resolution. The overall structure of EF-EG2 has an (α/α)6 barrel fold which contains a putative active-site cleft and a negatively charged surface. This structural information helps us understand the catalytic and cold adaptation mechanisms of EF-EG2.

Crystal structure of a GH1 β-glucosidase from Hamamotoa singularis.

Project description:A GH1 β-glucosidase from the fungus Hamamotoa singularis (HsBglA) has high transgalactosylation activity and efficiently converts lactose to galactooligosaccharides. Consequently, HsBglA is among the most widely used enzymes for industrial galactooligosaccharide production. Here, we present the first crystal structures of HsBglA with and without 4'-galactosyllactose, a tri-galactooligosaccharide, at 3.0 and 2.1 Å resolutions, respectively. These structures reveal details of the structural elements that define the catalytic activity and substrate binding of HsBglA, and provide a possible interpretation for its high catalytic potency for transgalactosylation reaction.

The crystal structure of human interferon beta at 2.2-A resolution.

Project description:Type I interferons (IFNs) are helical cytokines that have diverse biological activities despite the fact that they appear to interact with the same receptor system. To achieve a better understanding of the structural basis for the different activities of alpha and beta IFNs, we have determined the crystal structure of glycosylated human IFN-beta at 2.2-A resolution by molecular replacement. The molecule adopts a fold similar to that of the previously determined structures of murine IFN-beta and human IFN-alpha2b but displays several distinct structural features. Like human IFN-alpha2b, human IFN-beta contains a zinc-binding site at the interface of the two molecules in the asymmetric unit, raising the question of functional relevance for IFN-beta dimers. However, unlike the human IFN-alpha2b dimer, in which homologous surfaces form the interface, human IFN-beta dimerizes with contact surfaces from opposite sides of the molecule. The relevance of the structure to the effects of point mutations in IFN-beta at specific exposed residues is discussed. A potential role of ligand-ligand interactions in the conformational assembly of IFN receptor components is discussed.
