Expression, purification, crystallization and preliminary crystallographic study of FtsA from methicillin-resistant Staphylococcus aureus.

ABSTRACT: FtsA from methicillin-resistant Staphylococcus aureus (MRSA) was cloned, overexpressed and purified. The protein was crystallized using the sitting-drop vapour-diffusion technique. A cocrystal with ?-?-imidoadenosine 5'-phosphate (AMPPNP; a nonhydrolysable ATP analogue) was grown using PEG 3350 as a precipitant at 293 K. X-ray diffraction data were collected to a resolution of 2.3 Å at 100 K. The crystal belonged to the monoclinic space group P2?, with unit-cell parameters a = 75.31, b = 102.78, c = 105.90 Å, ? = 96.54°. The calculated Matthews coefficient suggested that the asymmetric unit contained three or four monomers.

Cloning, expression, purification, crystallization and preliminary X-ray diffraction studies of NAD synthetase from methicillin-resistant Staphylococcus aureus.

Project description:Staphylococcus aureus is an important human and animal pathogen that causes a wide range of infections. The prevalence of multidrug-resistant S. aureus strains in both hospital and community settings makes it imperative to characterize new drug targets to combat S. aureus infections. In this context, enzymes involved in NAD metabolism and synthesis are significant drug targets as NAD is a central player in several cellular processes. NAD synthetase catalyzes the last step in the biosynthesis of nicotinamide adenine dinucleotide, making it a crucial intermediate enzyme linked to the biosynthesis of several amino acids, purine and pyrimidine nucleotides, coenzymes and antibiotics.

Cloning, expression, purification, crystallization and preliminary X-ray diffraction studies of N-acetylneuraminate lyase from methicillin-resistant Staphylococcus aureus.

Project description:The enzyme N-acetylneuraminate lyase (EC 4.1.3.3) is involved in the metabolism of sialic acids. Specifically, the enzyme catalyzes the retro-aldol cleavage of N-acetylneuraminic acid to form N-acetyl-D-mannosamine and pyruvate. Sialic acids comprise a large family of nine-carbon amino sugars, all of which are derived from the parent compound N-acetylneuraminic acid. In recent years, N-acetylneuraminate lyase has received considerable attention from both mechanistic and structural viewpoints and has been recognized as a potential antimicrobial drug target. The N-acetylneuraminate lyase gene was cloned from methicillin-resistant Staphylococcus aureus genomic DNA, and recombinant protein was expressed and purified from Escherichia coli BL21?(DE3). The enzyme crystallized in a number of crystal forms, predominantly from PEG precipitants, with the best crystal diffracting to beyond 1.70?Å resolution in space group P2?. Molecular replacement indicates the presence of eight monomers per asymmetric unit. Understanding the structural biology of N-acetylneuraminate lyase in pathogenic bacteria, such as methicillin-resistant S. aureus, will provide insights for the development of future antimicrobials.

Cloning, expression, purification, crystallization and preliminary X-ray diffraction analysis of N-acetylmannosamine kinase from methicillin-resistant Staphylococcus aureus.

Project description:N-Acetylmannosamine kinase (EC 2.7.1.60) is involved in the catabolism of sialic acid for many bacterial pathogens implicated in human disease such as Escherichia coli, Staphylococcus aureus, Vibrio cholerae and V. vulnificus. Interestingly, some human commensals and bacterial pathogens can scavenge sialic acids from their surrounding environment and degrade them as a source of carbon, nitrogen and energy. This process requires a cluster of genes known as the `Nan-Nag cluster', which have proven to be essential for S. aureus growth on sialic acids, suggesting that the pathway is a viable antimicrobial drug target. The enzyme N-acetylmannosamine kinase is involved in the catabolism of sialic acid, transferring a phosphate group from adenosine-5'-triphosphate to the C6 position of N-acetylmannosamine to generate N-acetylmannosamine-6-phosphate. The gene was cloned into an appropriate expression vector; recombinant protein was expressed in E. coli BL21 (DE3) cells and purified via anion-exchange chromatography, hydrophobic interaction chromatography and size-exclusion chromatography. Purified N-acetylmannosamine kinase was screened for crystallization. The best crystal diffracted to a resolution of beyond 2.6 Å in space group P2. Understanding the structural nature of this enzyme from methicillin-resistant S. aureus will provide insights necessary for the development of future antimicrobials.

Cloning, purification, crystallization and preliminary X-ray crystallographic analysis of MCAT from Staphylococcus aureus.

Project description:Malonyl-CoA:acyl-carrier protein transacylase (MCAT), encoded by the fabd gene, is a key enzyme in type II fatty-acid biosynthesis. It is responsible for transferring the malonyl group from malonyl-CoA to the holo acyl-carrier protein (ACP). Since the type II system differs from the type I system that mammals use, it has received enormous attention as a possible antibiotic target. In particular, only a single isoform of MCAT has been reported and a continuous coupled enzyme assay has been developed. MCAT from Staphylococcus aureus was overexpressed in Escherichia coli and the protein was purified and crystallized. Diffraction data were collected to 1.2 A resolution. The crystals belonged to space group P2(1), with unit-cell parameters a = 41.608, b = 86.717, c = 43.163 A, alpha = gamma = 90, beta = 106.330 degrees . The asymmetric unit contains one SaMCAT molecule.

Cloning, expression, purification, crystallization and preliminary X-ray diffraction analysis of N-acetylmannosamine-6-phosphate 2-epimerase from methicillin-resistant Staphylococcus aureus.

Project description:Sialic acids are one of the most important carbohydrate classes in biology. Some bacterial pathogens can scavenge sialic acids from their surrounding environment and degrade them as a source of carbon, nitrogen and energy. This sequestration and subsequent catabolism of sialic acid require a cluster of genes known as the `Nan-Nag' cluster. The enzymes coded by these genes are important for pathogen colonization and persistence. Importantly, the Nan-Nag genes have proven to be essential for Staphylococcus aureus growth on sialic acids, suggesting that the pathway is a viable antibiotic drug target. The enzyme N-acetylmannosamine-6-phosphate 2-epimerase is involved in the catabolism of sialic acid; specifically, the enzyme converts N-acetylmannosamine-6-phosphate into N-acetylglucosamine-6-phosphate. The gene was cloned into an appropriate expression vector, and recombinant protein was expressed in Escherichia coli BL21 (DE3) cells and purified via a three-step procedure. Purified N-acetylmannosamine-6-phosphate 2-epimerase was screened for crystallization. The best crystal diffracted to a resolution of beyond 1.84 Å in space group P21212. Understanding the structural nature of this enzyme from methicillin-resistant S. aureus will provide us with the insights necessary for the development of future antibiotics.

Purification, crystallization and data collection of methicillin-resistant Staphylococcus aureus Sar2676, a pantothenate synthetase.

Project description:Sar2676, a pantothenate synthetase with a molecular weight of 31 419 Da from methicillin-resistant Staphylococcus aureus, has been expressed, purified and crystallized at 293 K. The protein crystallizes in a primitive triclinic lattice, with unit-cell parameters a = 45.3, b = 60.5, c = 117.6 A, alpha = 87.2, beta = 81.2, gamma = 68.4 degrees . A complete data set has been collected to 2.3 A resolution at the ESRF. Consideration of the likely solvent content suggested the asymmetric unit to contain four molecules. This has been confirmed by molecular-replacement phasing calculations, which give a solution with four monomers using a monomer of pantothenate synthetase from Escherichia coli (PDB code 1iho), which is 41% identical to Sar2676, as a search model.
