Purification, crystallization and preliminary X-ray analysis of NtdA, a putative pyridoxal phosphate-dependent aminotransferase from Bacillus subtilis.

ABSTRACT: NtdA is a putative sugar aminotransferase that is required for the synthesis of 3,3'-neotrehalosadiamine. The enzyme was purified to homogeneity by means of Ni(2+)-affinity chromatography and was crystallized using the microbatch method. X-ray diffraction data were collected from a single crystal to 2.3 A resolution at the Canadian Light Source (CLS). The crystals belonged to space group P2(1), with unit-cell parameters a = 50.3, b = 106.7, c = 96.7 A, beta = 96.2 degrees, and contained two molecules per asymmetric unit.

Purification, crystallization and preliminary X-ray analysis of a putative nucleotide phosphohydrolase, YpgQ, from Bacillus subtilis.

Project description:The histidine-aspartate (HD) domain exerts phosphohydrolase activity on nucleotides and functions in nucleotide metabolism. Sequence analysis suggested that YpgQ from Bacillus subtilis contains the HD domain, but the structure and function of YpgQ remain to be revealed. The recombinant YpgQ protein was overexpressed in an Escherichia coli cell expression system and was purified to homogeneity by Ni-NTA affinity and anion-exchange chromatography. Crystals in space group P2₁ were obtained in PEG 600 solutions and diffracted X-rays to 2.3 Å resolution. Moreover, X-ray fluorescence scans on YpgQ crystals demonstrated the metal-binding ability of YpgQ.

Expression, purification, crystallization and preliminary X-ray analysis of ribitol-5-phosphate cytidylyltransferase from Bacillus subtilis.

Project description:TarI is a ribitol-5-phosphate cytidylyltransferase that catalyzes the formation of CDP-ribitol, which is involved in the biosynthesis of wall teichoic acids, from CTP and ribitol 5-phosphate. TarI from Bacillus subtilis (BsTarI) was purified and crystallized using the sitting-drop vapour-diffusion method. The crystals diffracted to a resolution of 1.78 Å and belonged to the monoclinic space group C2, with unit-cell parameters a = 103.74, b = 60.97, c = 91.80 Å, β = 113.48°. The initial structural model indicated that the crystals of BsTarI contained a dimer in the asymmetric unit.

Cloning, purification and preliminary crystallographic analysis of a putative pyridoxal kinase from Bacillus subtilis.

Project description:Pyridoxal kinases (PdxK) are able to catalyse the phosphorylation of three vitamin B(6) precursors, pyridoxal, pyridoxine and pyridoxamine, to their 5'-phosphates and play an important role in the vitamin B(6) salvage pathway. Recently, the thiD gene of Bacillus subtilis was found to encode an enzyme which has the activity expected of a pyridoxal kinase despite its previous assignment as an HMPP kinase owing to higher sequence similarity. As such, this enzyme would appear to represent a new class of ;HMPP kinase-like' pyridoxal kinases. B. subtilis thiD has been cloned and the protein has been overexpressed in Escherichia coli, purified and subsequently crystallized in a binary complex with ADP and Mg(2+). X-ray diffraction data have been collected from crystals to 2.8 A resolution at 100 K. The crystals belong to a primitive tetragonal system, point group 422, and analysis of the systematic absences suggest that they belong to one of the enantiomorphic pair of space groups P4(1)2(1)2 or P4(3)2(1)2. Consideration of the space-group symmetry and unit-cell parameters (a = b = 102.9, c = 252.6 A, alpha = beta = gamma = 90 degrees ) suggest that the crystals contain between three and six molecules in the asymmetric unit. A full structure determination is under way to provide insights into aspects of the enzyme mechanism and substrate specificity.

Purification, crystallization and preliminary X-ray diffraction experiment of nattokinase from Bacillus subtilis natto.

Project description:Nattokinase is a single polypeptide chain composed of 275 amino acids (molecular weight 27,724) which displays strong fibrinolytic activity. Moreover, it can activate other fibrinolytic enzymes such as pro-urokinase and tissue plasminogen activator. In the present study, native nattokinase from Bacillus subtilis natto was purified using gel-filtration chromatography and crystallized to give needle-like crystals which could be used for X-ray diffraction experiments. The crystals belonged to space group C2, with unit-cell parameters a=74.3, b=49.9, c=56.3?Å, ?=95.2°. Diffraction images were processed to a resolution of 1.74?Å with an Rmerge of 5.2% (15.3% in the highest resolution shell) and a completeness of 69.8% (30.0% in the highest resolution shell). This study reports the first X-ray diffraction analysis of nattokinase.

Purification, crystallization and preliminary X-ray analysis of inositol dehydrogenase (IDH) from Bacillus subtilis.

Project description:Inositol dehydrogenase (IDH) is an enzyme that catalyses the NAD(+)-dependent oxidation of myo-inositol to scyllo-inosose. The enzyme has been purified to homogeneity by means of Ni(2+)-affinity chromatography and was crystallized in both native and selenomethionine (SeMet) labelled forms using the microbatch method. SAD X-ray diffraction data were collected to 2.0 A resolution from a SeMet-labelled crystal at the Advanced Photon Source (APS) and a MAD data set was collected to 1.75 A resolution at the Canadian Light Source (CLS); this is the first reported anomalous diffraction experiment from the CLS. The crystals belong to space group I222 and contain one molecule per asymmetric unit.

Purification, crystallization and X-ray crystallographic studies on a putative methyltransferase, YtqB, from Bacillus subtilis.

Project description:S-Adenosyl-L-methionine (SAM)-dependent methyltransferases (MTases) catalyze the transfer of a methyl group from a SAM cofactor to specific substrate molecules, including small chemicals, proteins, DNAs and RNAs, and are required for various cellular functions, such as regulation of gene expression and biosynthesis of metabolites. Bacillus subtilis YtqB is a putative SAM-dependent MTase whose biological function has not been characterized. To provide biochemical and structural insights into the role of YtqB in bacteria, the recombinant YtqB protein was overexpressed in the Escherichia coli expression system and purified by chromatographic methods. YtqB crystals were obtained in PEG-containing conditions and diffracted to 1.68?Å resolution. The YtqB crystals belonged to space group P212121, with two molecules in the asymmetric unit.
