Purification, crystallization and preliminary X-ray diffraction analysis of aspartate semialdehyde dehydrogenase (Rv3708c) from Mycobacterium tuberculosis.

ABSTRACT: Aspartate semialdehyde dehydrogenase from Mycobacterium tuberculosis (Asd, ASADH, Rv3708c), which is the second enzyme in the lysine/homoserine-biosynthetic pathways, has been expressed heterologously in Escherichia coli. The enzyme was purified using affinity and gel-filtration chromatographic techniques and crystallized in two different crystal forms. Preliminary diffraction data analysis suggested the presence of up to four monomers in the asymmetric unit of the orthorhombic crystal form A and of one or two monomers in the cubic crystal form B.

Cloning, overexpression, purification, crystallization and preliminary X-ray diffraction analysis of Rv0241c (HtdX) from Mycobacterium tuberculosis H37Rv.

Project description:Rv0241c (HtdX) is a putative (3R)-hydroxyacyl-CoA dehydratase of Mycobacterium tuberculosis. The htdX gene belongs to a conserved operon and is expressed in mycobacteria in the presence of several fatty-acid synthase II drugs. To elucidate the structure of HtdX, the protein was cloned, overexpressed, purified to homogeneity and crystallized. The protein was crystallized from two conditions: (i) 3 M sodium chloride, 0.1 M Na HEPES pH 8.0 and (ii) 2.5 M sodium chloride, 0.1 M Tris-HCl pH 8.5. A complete diffraction data set was collected from crystals from both conditions. The crystal from the first condition diffracted to 2.3 Å resolution and belonged to space group I41, with unit-cell parameters a=b=61.51, c=143.81 Å. Crystals from the second condition diffracted to 3.1 Å resolution and belonged to space group P4₃2₁2 or P4₁2₁2, with unit-cell parameters a=b=63.67, c=140.88 Å. Both crystals contained one molecule in the asymmetric unit.

Expression, purification, crystallization and preliminary X-ray diffraction analysis of the transcriptional repressor SirR from Mycobacterium tuberculosis H37Rv.

Project description:SirR, a metal-dependent transcriptional repressor from Mycobacterium tuberculosis (Rv2788), was cloned in pQE30 expression vector with an N-terminal His(6) tag for heterologous overexpression in Escherichia coli M15 (pREP4) cells and purified to homogeneity using chromatographic procedures. The purified protein was crystallized using the sitting-drop vapour-diffusion technique. The crystals belonged to the tetragonal space group P4(1)2(1)2/P4(3)2(1)2, with unit-cell parameters a = 105.21, b = 105.21, c = 144.85 A. The X-ray diffraction data were processed to a maximum resolution of 2.5 A. The Matthews coefficient suggests the presence of two (V(M) = 4.01 A(3) Da(-1)) to four (V(M) = 2.0 A(3) Da(-1)) molecules in the asymmetric unit. Calculation of the self-rotation function shows a crystallographic fourfold symmetry axis along the z axis (chi = 90 degrees) and also a twofold symmetry axis around the z axis (chi = 180 degrees).

Cloning, expression, purification, crystallization and preliminary X-ray diffraction analysis of tetrahydrodipicolinate-N-succinyltransferase (Rv1201c) from Mycobacterium tuberculosis.

Project description:Tetrahydrodipicolinate-N-succinyltransferase from Mycobacterium tuberculosis (DapD, Rv1201c) has been cloned, heterologously expressed in Escherichia coli, purified using standard chromatographic techniques and crystallized in the cubic space group I23 or I2(1)3. Preliminary diffraction data analysis indicates the presence of five molecules per asymmetric unit. Furthermore, the data exhibit icosahedral point-group symmetry. One possible explanation for this is that the enzyme assembles into a 60-mer exhibiting 235 point-group symmetry and crystallizes as such in space group I23. In this case, the combination of crystallographic and noncrystallographic symmetry elements results in an arrangement of the icosahedrons in the cubic crystal with one pentamer in the asymmetric unit. Another explanation is that the packing of the molecules itself mimics icosahedral symmetry. In this case both space groups I23 and I2(1)3 would be possible.

Cloning, expression, purification, crystallization and preliminary X-ray diffraction analysis of succinyl-diaminopimelate desuccinylase (Rv1202, DapE) from Mycobacterium tuberculosis.

Project description:Succinyl-diaminopimelate desuccinylase from Mycobacterium tuberculosis (DapE, Rv1202) has been cloned, heterologously expressed in Escherichia coli and purified using standard chromatographic techniques. Diffraction-quality crystals were obtained at acidic pH from ammonium sulfate and PEG and diffraction data were collected from two crystals to resolutions of 2.40 and 2.58 Å, respectively. The crystals belonged to the monoclinic space group P2(1), with unit-cell parameters a = 79.7, b = 76.0, c = 82.9 Å, β = 119°. The most probable content of the asymmetric unit was two molecules of DapE, which would correspond to a solvent content of 56%. Both examined crystals turned out to be pseudo-merohedrally twinned, with twin operator -h, -k, h + l and twin fractions of approximately 0.46 and 0.16, respectively.

Expression, purification, crystallization and preliminary X-ray diffraction analysis of the aspartate transcarbamoylase domain of human CAD.

Project description:Aspartate transcarbamoylase (ATCase) catalyzes the synthesis of N-carbamoyl-L-aspartate from carbamoyl phosphate and aspartate in the second step of the de novo biosynthesis of pyrimidines. In prokaryotes, the first three activities of the pathway, namely carbamoyl phosphate synthetase (CPSase), ATCase and dihydroorotase (DHOase), are encoded as distinct proteins that function independently or in noncovalent association. In animals, CPSase, ATCase and DHOase are part of a 243 kDa multifunctional polypeptide named CAD. Up-regulation of CAD is essential for normal and tumour cell proliferation. Although the structures of numerous prokaryotic ATCases have been determined, there is no structural information about any eukaryotic ATCase. In fact, the only detailed structural information about CAD is that it self-assembles into hexamers and trimers through interactions of the ATCase domains. Here, the expression, purification and crystallization of the ATCase domain of human CAD is reported. The recombinant protein, which was expressed in bacteria and purified with good yield, formed homotrimers in solution. Crystallization experiments both in the absence and in the presence of the inhibitor PALA yielded small crystals that diffracted X-rays to 2.1 Å resolution using synchrotron radiation. The crystals appeared to belong to the hexagonal space group P6(3)22, and Matthews coefficient calculation indicated the presence of one ATCase subunit per asymmetric unit, with a solvent content of 48%. However, analysis of the intensity statistics suggests a special case of the P21 lattice with pseudo-symmetry and possibly twinning.

Cloning, expression, purification, crystallization and preliminary X-ray diffraction analysis of the regulatory domain of aspartokinase (Rv3709c) from Mycobacterium tuberculosis.

Project description:The regulatory domain of Mycobacterium tuberculosis aspartokinase (Mtb-AK, Mtb-Ask, Rv3709c) has been cloned, heterologously expressed in Escherichia coli and purified using standard chromatographic techniques. Screening for initial crystallization conditions using the regulatory domain (AK-?) in the presence of the potential feedback inhibitor threonine identified four conditions which yielded crystals suitable for X-ray diffraction analysis. From these four conditions five different crystal forms of Mtb-AK-? resulted, three of which belonged to the orthorhombic system, one to the tetragonal system and one to the monoclinic system. The highest resolution (1.6?Å) was observed for a crystal form belonging to space group P2(1)2(1)2(1), with unit-cell parameters a=53.70, b=63.43, c=108.85?Å and two molecules per asymmetric unit.

Purification, crystallization and preliminary X-ray diffraction experiments on the breakage-reunion domain of the DNA gyrase from Mycobacterium tuberculosis.

Project description:Mycobacterium tuberculosis DNA gyrase, a nanomachine that is involved in the regulation of DNA topology, is the only type II topoisomerase present in this organism and hence is the sole target for fluoroquinolone action. The breakage-reunion domain of the A subunit plays an essential role in DNA binding during the catalytic cycle. Two constructs of 53 and 57 kDa (termed GA53BK and GA57BK) corresponding to this domain have been overproduced, purified and crystallized. Diffraction data were collected from four crystal forms. The resolution limits ranged from 4.6 to 2.7 angstrom depending on the crystal form. The best diffracting crystals belonged to space group C2, with a biological dimer in the asymmetric unit. This is the first report of the crystallization and preliminary X-ray diffraction analysis of the breakage-reunion domain of DNA gyrase from a species containing one unique type II topoisomerase.

Purification, crystallization and preliminary X-ray studies of MbtN (Rv1346) from Mycobacterium tuberculosis.

Project description:In Mycobacterium tuberculosis, the protein MbtN (Rv1346) catalyzes the formation of a double bond in the fatty-acyl moiety of the siderophore mycobactin, which is used by this organism to acquire essential iron. MbtN is homologous to acyl-CoA dehydrogenases, whose general role is to catalyze the ?,?-dehydrogenation of fatty-acyl-CoA conjugates. Mycobactins, however, contain a long unsaturated fatty-acid chain with an unusual cis double bond conjugated to the carbonyl group of the mycobactin core. To characterize the role of MbtN in the dehydrogenation of this fatty-acyl moiety, the enzyme has been expressed, purified and crystallized. The crystals diffracted to 2.3 Å resolution at a synchrotron source and were found to belong to the hexagonal space group H32, with unit-cell parameters a = b = 139.10, c = 253.09 Å, ? = ? = 90, ? = 120°.

Purification, crystallization and preliminary X-ray crystallographic studies of Rv3899c from Mycobacterium tuberculosis.

Project description:Rv3899c, a hypothetical protein from Mycobacterium tuberculosis that is conserved within the mycobacteria, is predicted to be secreted and has been found in culture filtrates. Here, Rv3899c has been cloned, expressed in Escherichia coli and purified using standard chromatographic techniques. The hanging-drop vapour-diffusion method with PEG 3350 as a precipitant was used to crystallize the protein. N-terminal sequencing results showed that the amino-acid sequence of the crystallized protein began with GATAG, indicating that it is a fragment containing residues 184-410 of Rv3899c. Rv3899c184-410 crystals exhibited the symmetry of space group P2(1)2(1)2(1), with unit-cell parameters a=49.88, b=54.72, c=75.52?Å, ?=?=?=90°, and diffracted to a resolution of 1.90?Å.
