The outer membrane protein OprM of Pseudomonas aeruginosa is involved in intrinsic and mutational multiple-antibiotic resistance as part of two resistance-nodulation-division efflux systems. The crystal structure of TolC, a homologous protein in Escherichia coli, was recently published (V. Koronakis, A. Sharff, E. Koronakis, B. Luisl, and C. Hughes, Nature 405:914-919, 2000), demonstrating a di...
The cold-shock domain has a deceptively simple architecture but supports complex biology. It is conserved from bacteria to man and representatives in all kingdoms of life. Bacterial proteins consist single some, not are induced by cold shock. Cold-shock domains human often associated with natively unfolded protein segments more rarely other folded domains. share five-stranded all-antiparallel ?...
The 3-polyprenyl-4-hydroxybenzoate decarboxylase (UbiD) catalyzes the conversion of 3-polyprenyl-4-hydroxybenzoate to 2-polyprenylphenol in the biosynthesis of ubiquinone. Pseudomonas aeruginosa contains two genes (PA0254 and PA5237) that are related in sequence to putative UbiD enzymes. A bioinformatics analysis suggests that the UbiD sequence family can be divided into two subclasses, with PA...
Autotransporters (ATs) are a family of bacterial proteins containing a C-terminal β-barrel-forming domain that facilitates the translocation of N-terminal passenger domain whose functions range from adhesion to proteolysis. Genetic replacement of the native passenger domain with heterologous proteins is an attractive strategy not only for applications such as biocatalysis, live-cell vaccines, a...
Autotransporters are secreted proteins that are assembled into the outer membrane of bacterial cells. The passenger domains of autotransporters are crucial for bacterial pathogenesis, with some remaining attached to the bacterial surface while others are released by proteolysis. An enigma remains as to whether autotransporters should be considered a class of secretion system, or simply a class ...
Cholesteryl ester transfer protein (CETP) mediates the net transfer of cholesteryl esters (CEs) from atheroprotective high-density lipoproteins (HDLs) to atherogenic low-density lipoproteins (LDLs) or very-low-density lipoproteins (VLDLs). Inhibition of CETP raises HDL cholesterol (good cholesterol) levels and reduces LDL cholesterol (bad cholesterol) levels, making it a promising drug target f...
The X-ray structures of the ligand free (apo) and the Mg(2+)*o-succinylbenzoate (OSB) product complex of o-succinylbenzoate synthase (OSBS) from Escherichia coli have been solved to 1.65 and 1.77 A resolution, respectively. The structure of apo OSBS was solved by multiple isomorphous replacement in space group P2(1)2(1)2(1); the structure of the complex with Mg(2+)*OSB was solved by molecular r...
this work presents a simulation approach to the design and economic evaluation of fuel oil hydrotreating processes for control of so2 and nox emission in an iranian steam power plant. minimum amount of required fuel oil desulphurization was calculated from the limit of so2 emissions of power plants in two different scenarios based on (i) european and (ii) iranian so2 emission standards. based o...
Radical S-adenosylmethionine (SAM) enzymes use a [4Fe-4S] cluster to generate a 5'-deoxyadenosyl radical. Canonical radical SAM enzymes are characterized by a β-barrel-like fold and SAM anchors to the differentiated iron of the cluster, which is located near the amino terminus and within the β-barrel, through its amino and carboxylate groups. Here we show that ThiC, the thiamin pyrimidine synth...
