Title: Cloning, expression, purification, crystallization and preliminary X-ray diffraction analysis of the glutamate-1-semialdehyde aminotransferase from Bacillus subtilis

Abstract

Crystals of glutamate-1-semialdehyde aminotransferase (GSAT) from B. subtilis were obtained and diffraction data were collected to 2.0 Å resolution. 5-Aminolevulinic acid (ALA) is the first committed universal precursor in the tetrapyrrole-biosynthesis pathway. Plants, algae and many other bacteria synthesize ALA from glutamate by a C5 pathway in which the carbon skeleton of glutamate is converted into ALA by a series of enzymes. Glutamate-1-semialdehyde aminotransferase (GSAT) is the last enzyme in this pathway. The gene that codes for GSAT was amplified from the cDNA library of Bacillus subtilis and overexpressed in Escherichia coli strain BL21(DE3). The protein was purified and crystallized. Well diffracting single crystals were obtained by the hanging-drop vapour-diffusion method. Preliminary X-ray diffraction studies yielded excellent diffraction data to a resolution of 2.0 Å.

  • The nitrile hydratase from the themophilic B. smithii SC-J05-1 (Bs NHase) has been purified, cloned and crystallized. Nitrile hydratase (NHase) converts nitriles to the corresponding amides and is recognized as having important industrial applications. Purification, cloning, crystallization and initial crystallographic studies of the NHase from Bacillus smithii SC-J05-1 (Bs NHase) were conducted to analyze the activity, specificity and thermal stability of this hydrolytic enzyme. Bs NHase was purified to homogeneity from microbial cells of B. smithii SC-J05-1 and the nucleotide sequences of both the α- and β-subunits were determined. Purified Bs NHase was used for crystallization and several crystal formsmore » were obtained by the vapour-diffusion method. Microseeding and the addition of magnesium ions were essential components to obtain crystals suitable for X-ray diffraction analysis.« less
  • 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{sup +}. 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{sup +} and the crystal diffracted to 2.38 {angstrom} resolution. The crystal belonged to space group P3, with unit-cell parameters a = b = 171.04, c = 96.27 {angstrom}. BsLDH-H171C was also crystallized asmore » the apoenzyme and in complex with NAD{sup +}, and data sets were collected to 2.20 and 2.49 {angstrom} resolution, respectively. Both BsLDH-H171C crystals belonged to space group P3, with unit-cell parameters a = b = 133.41, c = 99.34 {angstrom} and a = b = 133.43, c = 99.09 {angstrom}, respectively. Tetramers were observed in the asymmetric units of all three crystals.« less
  • Francisella tularensis, a potential bioweapon, causes a rare infectious disease called tularemia in humans and animals. The macrophage growth locus A (MglA) protein from F. tularensis associates with RNA polymerase to positively regulate the expression of multiple virulence factors that are required for its survival and replication within macrophages. The MglA protein was overproduced in Escherichia coli, purified and crystallized. The crystals diffracted to 7.5 {angstrom} resolution at the Advanced Photon Source, Argonne National Laboratory and belonged to the hexagonal space group P6{sub 1} or P6{sub 5}, with unit-cell parameters a = b = 125, c = 54 {angstrom}.
  • M. tuberculosis diaminopimelate decarboxylase, the enzyme that catalyzes the final step of lysine biosynthesis, has been cloned, expressed, purified and crystallized in the absence of cofactor or substrate. Diaminopimelate decarboxylase from Mycobacterium tuberculosis (LysA, DAPDC, Rv1293) has been cloned and heterologously expressed in Escherichia coli, purified using standard chromatographic techniques and crystallized. Preliminary diffraction data analysis suggests the presence of a homotetramer in the asymmetric unit.
  • Propionate kinase (TdcD) from S. typhimurium has been expressed, purified and crystallized. A diffraction data set has been collected to 2.2 Å resolution. In the cell, propionate is mainly formed during β-oxidation of odd-numbered carbon-chain fatty acids, fermentation of carbohydrates and degradation of the amino acids threonine, valine, isoleucine and methionine. Recently, it has been shown that l-threonine is non-oxidatively cleaved to propionate via 2-ketobutyrate. The last step in this process, conversion of propionyl phosphate and ADP to propionate and ATP, is catalysed by propionate kinase (EC 2.7.1.–). Here, the cloning of propionate kinase (molecular weight 44 kDa) from Salmonellamore » typhimurium with an N-terminal hexahistidine affinity tag and its overexpression in Escherichia coli are reported. Purified propionate kinase was found to cocrystallize with ADP in the hanging-drop vapour-diffusion and microbatch methods. Crystals belong to space group P3{sub 1}21 or P3{sub 2}21, with unit-cell parameters a = b = 111.47, c = 66.52 Å. A complete data set to 2.2 Å resolution has been collected using an image-plate detector system mounted on a rotating-anode X-ray generator.« less
