Expression, crystallization and preliminary X-ray crystallographic analysis of aldehyde dehydrogenase (ALDH) from Bacillus cereus.

ABSTRACT: Aldehyde dehydrogenase (ALDH) catalyses the oxidation of aldehydes using NAD(P)(+) as a cofactor. Most aldehydes are toxic at low levels. ALDHs are used to regulate metabolic intermediate aldehydes. The aldh gene from Bacillus cereus was cloned and the ALDH protein was expressed, purified and crystallized. A crystal of the ALDH protein diffracted to 2.6?Å resolution and belonged to the monoclinic space group P21, with unit-cell parameters a = 83.5, b = 93.3, c = 145.5?Å, ? = 98.05°. Four protomers were present in the asymmetric unit, with a corresponding VM of 2.55?Å(3)?Da(-1) and a solvent content of 51.8%.

Purification, crystallization and preliminary X-ray crystallographic analysis of glycosyltransferase-1 from Bacillus cereus.

Project description:Glycosyltransferases (GTs), which are distributed widely in various organisms, including bacteria, fungi, plants and animals, play a role in synthesizing biological compounds. Glycosyltransferase-1 from Bacillus cereus (BcGT-1), which is capable of transferring glucose to small molecules such as kaempferol and quercetin, has been identified as a member of the family 1 glycosyltransferases which utilize uridine diphosphate glucose (UDP-glucose) as the sugar donor. BcGT-1 (molecular mass 45.5 kDa) has been overexpressed, purified and crystallized using the hanging-drop vapour-diffusion method. According to X-ray diffraction of BcGT-1 crystals to 2.10 Å resolution, the crystal belonged to space group P1, with unit-cell parameters a = 54.56, b = 84.81, c = 100.12 Å, α = 78.36, β = 84.66, γ = 84.84°. Preliminary analysis indicates the presence of four BcGT-1 molecules in the asymmetric unit with a solvent content of 50.27%.

Project description:L-Lactate dehydrogenase (LDH) is an important enzyme involved in the last step of glycolysis that catalyzes the reversible conversion of pyruvate to L-lactate with the simultaneous oxidation of NADH to NAD(+). In this study, wild-type LDH from Bacillus subtilis (BsLDH-WT) and the H171C mutant (BsLDH-H171C) were expressed in Escherichia coli and purified to near-homogeneity. BsLDH-WT was crystallized in the presence of fructose 1,6-bisphosphate (FBP) and NAD(+) and the crystal diffracted to 2.38 Å resolution. The crystal belonged to space group P3, with unit-cell parameters a = b = 171.04, c = 96.27 Å. BsLDH-H171C was also crystallized as the apoenzyme and in complex with NAD(+), and data sets were collected to 2.20 and 2.49 Å resolution, respectively. Both BsLDH-H171C crystals belonged to space group P3, with unit-cell parameters a = b = 133.41, c = 99.34 Å and a = b = 133.43, c = 99.09 Å, respectively. Tetramers were observed in the asymmetric units of all three crystals.

Expression, crystallization and preliminary X-ray crystallographic analysis of alcohol dehydrogenase (ADH) from Kangiella koreensis.

Project description:Alcohol dehydrogenases (ADHs) are a group of dehydrogenase enzymes that facilitate the interconversion between alcohols and aldehydes or ketones with the reduction of NAD(+) to NADH. In bacteria, some alcohol dehydrogenases catalyze the opposite reaction as part of fermentation to ensure a constant supply of NAD(+). The adh gene from Kangiella koreensis was cloned and the protein (KkADH) was expressed, purified and crystallized. A KkADH crystal diffracted to 2.5?Å resolution and belonged to the monoclinic space group P2(1), with unit-cell parameters a = 94.1, b = 80.9, c = 115.6?Å, ? = 111.9°. Four monomers were present in the asymmetric unit, with a corresponding VM of 2.55?Å(3)?Da(-1) and a solvent content of 51.8%.

Crystallization and preliminary X-ray analysis of a phosphopentomutase from Bacillus cereus.

Project description:Phosphopentomutases (PPMs) interconvert D-ribose 5-phosphate and alpha-D-ribose 1-phosphate to link glucose and nucleotide metabolism. PPM from Bacillus cereus was overexpressed in Escherichia coli, purified to homogeneity and crystallized. Bacterial PPMs are predicted to contain a di-metal reaction center, but the catalytically relevant metal has not previously been identified. Sparse-matrix crystallization screening was performed in the presence or absence of 50 mM MnCl(2). This strategy resulted in the formation of two crystal forms from two chemically distinct conditions. The crystals that formed with 50 mM MnCl(2) were more easily manipulated and diffracted to higher resolution. These results suggest that even if the catalytically relevant metal is not known, the crystallization of putative metalloproteins may still benefit from supplementation of the crystallization screens with potential catalytic metals.

Crystallization and preliminary X-ray crystallographic analysis of rabbit L-gulonate 3-dehydrogenase.

Project description:Rabbit L-gulonate 3-dehydrogenase was crystallized using the oil-microbatch method at 295 K. X-ray diffraction data were collected to 1.70 A resolution from a crystal at 100 K using synchrotron radiation. The crystal belongs to the C-centred monoclinic space group C2, with unit-cell parameters a = 71.81, b = 69.08, c = 65.64 A, beta = 102.7 degrees. Assuming the presence of a monomeric protomer in the asymmetric unit gives a V(M) value of 2.21 A(3) Da(-1) and a solvent content of 44.4%. A cocrystal with NADH, which was isomorphous to the apo form, was also prepared and diffraction data were collected to 1.85 A resolution using Cu Kalpha radiation at 100 K.

Crystallization and preliminary X-ray crystallographic studies of succinic semialdehyde dehydrogenase from Streptococcus pyogenes.

Project description:Succinic semialdehyde dehydrogenase (SSADH) plays a critical role in the metabolism of the inhibitory neurotransmitter γ-aminobutyric acid (GABA) and catalyzes the NAD(P)(+)-coupled oxidation of succinic semialdehyde (SSA) to succinic acid (SA). SSADH from Streptococcus pyogenes has been purified and crystallized as the apoenzyme and in a complex with NAD(+). The crystals of native and NAD(+)-complexed SSADH diffracted to resolutions of 1.6 and 1.7 Å, respectively, using a synchrotron-radiation source. Both crystals belonged to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 93.3, b = 100.3, c = 105.1 Å for the native crystal and a = 93.3, b = 100.3, c = 105.0 Å for the complex crystal. Preliminary molecular replacement confirmed the presence of one dimer in both crystals, corresponding to a Matthews coefficient (V(M)) of 2.37 Å(3) Da(-1) and a solvent content of 48.0%.

Overexpression, crystallization and preliminary X-ray crystallographic analysis of shikimate dehydrogenase from Archaeoglobus fulgidus.

Project description:Shikimate dehydrogenase (SDH), which catalyses the NADPH-dependent reduction of 3-dehydroshikimate to shikimate in the shikimate pathway, is an attractive target for the development of herbicides and antimicrobial agents. Previous structural studies have shown that SDH exists in two conformations, an open and a closed form, and it is believed that the conformational state is crucial to understanding its catalytic mechanism. In order to facilitate further structural comparisons among SDHs, including the conformational state, structural analysis of an SDH from Archaeoglobus fulgidus encoded by the Af2327 gene has been initiated. SeMet-labelled SDH from A. fulgidus was overexpressed in Escherichia coli and crystallized at 296 K using ammonium sulfate as a precipitant in order to use the MAD method for structure determination. Crystals of A. fulgidus SDH grown in the presence of NADP(+) diffracted to 2.8 Å resolution and belonged to the trigonal space group P3(2)21 (or P3(2)21), with unit-cell parameters a = 111.3, b = 111.3, c = 76.2 Å. Three diffraction data sets were collected. The asymmetric unit contains two monomers, with a corresponding V(M) of 2.34 Å(3) Da(-1) and a solvent content of 47% by volume.

The asymmetric unit contains a monomer, with a corresponding VM of 2.01 Å3 Da(-1) and a solvent content of 38.9% by volume.
