structural basis for hypermodification of the wobble uridine in trna by bifunctional enzyme mnmc.methylaminomethyl modification of uridine or 2-thiouridine (mnm5u34 or mnm5s2u34) at the wobble position of trnas specific for glutamate, lysine and arginine are observed in escherichia coli and allow for specific recognition of codons ending in a or g. in the biosynthetic pathway responsible for this post-transcriptional modification, the bifunctional enzyme mnmc catalyzes the conversion of its hypermodified substrate carboxymethylaminomethyl uridine (cmnm5u34) to mnm5u34. mnmc catalyzes the fl ...201323617613
role of yersinia pestis toxin complex family proteins in resistance to phagocytosis by polymorphonuclear leukocytes.yersinia pestis carries homologues of the toxin complex (tc) family proteins, which were first identified in other gram-negative bacteria as having potent insecticidal activity. the y. pestis tc proteins are neither toxic to fleas nor essential for survival of the bacterium in the flea, even though tc gene expression is highly upregulated and much more of the tc proteins yita and yipa are produced in the flea than when y. pestis is grown in vitro. we show that tc(+) and tc(-) y. pestis strains a ...201323959716
an alternative outer membrane secretion mechanism for an autotransporter protein lacking a c-terminal stable core.autotransporter (at) proteins are a broad class of virulence factors from gram-negative pathogens. at outer membrane (om) secretion appears simple in many regards, yet the mechanism that enables transport of the central at 'passenger' across the om remains unclear. om secretion efficiency for two at passengers is enhanced by approximately 20 kda stable core at the c-terminus of the passenger, but studies on a broader range of at proteins are needed in order to determine whether a stability diffe ...201324118465
early host cell targets of yersinia pestis during primary pneumonic plague.inhalation of yersinia pestis causes primary pneumonic plague, a highly lethal syndrome with mortality rates approaching 100%. pneumonic plague progression is biphasic, with an initial pre-inflammatory phase facilitating bacterial growth in the absence of host inflammation, followed by a pro-inflammatory phase marked by extensive neutrophil influx, an inflammatory cytokine storm, and severe tissue destruction. using a fret-based probe to quantitate injection of effector proteins by the y. pestis ...201324098126
analysis of autoinducer-2 quorum sensing in yersinia pestis.the autoinducer-2 (ai-2) quorum-sensing system has been linked to diverse phenotypes and regulatory changes in pathogenic bacteria. in the present study, we performed a molecular and biochemical characterization of the ai-2 system in yersinia pestis, the causative agent of plague. in strain co92, the ai-2 signal is produced in a luxs-dependent manner, reaching maximal levels of 2.5 μm in the late logarithmic growth phase, and both wild-type and pigmentation (pgm) mutant strains made equivalent l ...201323959719
context-dependent protein folding of a virulence peptide in the bacterial and host environments: structure of an sych-yoph chaperone-effector complex.yersinia pestis injects numerous bacterial proteins into host cells through an organic nanomachine called the type 3 secretion system. one such substrate is the tyrosine phosphatase yoph, which requires an interaction with a cognate chaperone in order to be effectively injected. here, the first crystal structure of a sych-yoph complex is reported, determined to 1.9 å resolution. the structure reveals the presence of (i) a nonglobular polypeptide in yoph, (ii) a so-called β-motif in yoph and (iii ...201323519663
the hemophore hasa from yersinia pestis (hasayp) coordinates hemin with a single residue, tyr75, and with minimal conformational change.hemophores from serratia marcescens (hasa(sm)) and pseudomonas aeruginosa (hasa(p)) bind hemin between two loops, which harbor the axial ligands h32 and y75. hemin binding to the y75 loop triggers closing of the h32 loop and enables binding of h32. because yersinia pestis hasa (hasa(yp)) presents a gln at position 32, we determined the structures of apo- and holo-hasa(yp). surprisingly, the q32 loop in apo-hasa(yp) is already in the closed conformation, but no residue from the q32 loop binds hem ...201323578210
[bioterrorism and pathogenic microorganisms].in recent years the use of pathogenic microorganisms in acts of bioterrorism has been the subject of major concern in many countries. this paper presents a possible application of viruses and bacteria for warfare and terrorist purposes, as well as a laboratory diagnosis to identify those agents. the viruses of smallpox (orthopoxvirus), of hemorrhagic fever and those belonging to filovirus have been highlighted, inter alia, as agents of human infection with bioterrorist intent. among the bacteria ...201324473660
reverse line blot macroarray for simultaneous detection and characterization of four biological warfare agents.the need for a rapid detection and characterization of biowarfare (bw) agents cannot be over emphasized. with diverse array of potential bw pathogen available presently, rapid identification of the pathogen is crucial, so that specific therapy and control measures can be initiated. we have developed a multiplex polymerase chain reaction based reverse line blot macroarray to simultaneously detect four pathogens of bw importance viz. bacillus anthracis, yersinia pestis, brucella melitensis and bur ...201324426077
applications of docking and molecular dynamic studies on the search for new drugs against the biological warfare agents bacillus anthracis and yersinia pestis.the fear of biological warfare agents (bwa) use by terrorists is the major concern of the security agencies and health authorities worldwide today. the non-existence of vaccines or drugs against most bwa and the possibility of genetic modified strains has turned the search for new drugs to a state of urgency. fast in silico techniques are, therefore, perfect tools for this task once they can quickly provide structures of several new lead compounds for further experimental work. here we try to pr ...201324341424
outer membrane proteins ail and ompf of yersinia pestis are involved in the adsorption of t7-related bacteriophage yep-phi.yep-phi is a t7-related bacteriophage specific to yersinia pestis, and it is routinely used in the identification of y. pestis in china. yep-phi infects y. pestis grown at both 20°c and 37°c. it is inactive in other yersinia species irrespective of the growth temperature. based on phage adsorption, phage plaque formation, affinity chromatography, and western blot assays, the outer membrane proteins of y. pestis ail and ompf were identified to be involved, in addition to the rough lipopolysacchar ...201324006436
exsa and lcrf recognize similar consensus binding sites, but differences in their oligomeric state influence interactions with promoter dna.exsa activates type iii secretion system (t3ss) gene expression in pseudomonas aeruginosa and is a member of the arac family of transcriptional regulators. arac proteins contain two helix-turn-helix (hth) dna binding motifs. one helix from each hth motif inserts into the major groove of the dna to make base-specific contacts with the promoter region. the amino acids that comprise the hth motifs of exsa are nearly identical to those in lcrf/virf, the activators of t3ss gene expression in the path ...201324142246
thiamine triphosphatase and the cyth superfamily of proteins.the cyth superfamily of proteins was named after its two founding members, the cyab adenylyl cyclase from aeromonas hydrophila, and the human 25-kda thiamine triphosphatase (thtpase). members of this superfamily of proteins exist in all organisms, including bacteria, archaeons, fungi, plants, and animals (except birds), and can be traced back to the last universal common ancestor. their sequences include several charged residues involved in divalent cation and triphosphate binding. indeed, all m ...201324021036
ail proteins of yersinia pestis and y. pseudotuberculosis have different cell binding and invasion activities.the yersinia pestis adhesin ail mediates host cell binding and facilitates delivery of cytotoxic yop proteins. ail from y. pestis and y. pseudotuberculosis is identical except for one or two amino acids at positions 43 and 126 depending on the y. pseudotuberculosis strain. ail from y. pseudotuberculosis strain ypiii has been reported to lack host cell binding ability, thus we sought to determine which amino acid difference(s) are responsible for the difference in cell adhesion. y. pseudotubercul ...201324386237

human single-chain urokinase is activated by the omptins pgte of salmonella enterica and pla of yersinia pestis despite mutations of active site residues.fibrinolysis is important in cell migration and tightly regulated by specific inhibitors and activators; of the latter, urokinase (upa) associates with enhancement of cell migration. active upa is formed through cleavage of the single-chain upa (scupa). the salmonella enterica strain 14028r cleaved human scupa at the peptide bond lys158-ile159, the site cleaved also by the physiological activator human plasmin. the cleavage led to activation of scupa, while no cleavage or activation were detecte ...201323763588
integrating high-content imaging and chemical genetics to probe host cellular pathways critical for yersinia pestis infection.the molecular machinery that regulates the entry and survival of yersinia pestis in host macrophages is poorly understood. here, we report the development of automated high-content imaging assays to quantitate the internalization of virulent y. pestis co92 by macrophages and the subsequent activation of host nf-κb. implementation of these assays in a focused chemical screen identified kinase inhibitors that inhibited both of these processes. rac-2-ethoxy-3 octadecanamido-1-propylphosphocholine ( ...201323383093
fast and simple detection of yersinia pestis applicable to field investigation of plague foci.yersinia pestis, the plague bacillus, has a rodent-flea-rodent life cycle but can also persist in the environment for various periods of time. there is now a convenient and effective test (f1-dipstick) for the rapid identification of y. pestis from human patient or rodent samples, but this test cannot be applied to environmental or flea materials because the f1 capsule is mostly produced at 37°c. the plasminogen activator (pla), a key virulence factor encoded by a y. pestis-specific plasmid, is ...201323383008
recombinant salmonella vaccination technology and its application to human bacterial pathogens.salmonella enterica is a gram-negative intracellular bacterial pathogen which causes salmonellosis in humans and animals. during the past several decades, extensive studies have shown that the attenuated salmonella vaccine vector is an optimal vehicle for delivering passenger antigens to mucosal sites to induce humoral, cellular, and mucosal immunity. this immunity leads to protection against challenges with the wild-type pathogens from which the passenger antigens were derived. a myriad of stud ...201323360265
evaluation of protective potential of yersinia pestis outer membrane protein antigens as possible candidates for a new-generation recombinant plague vaccine.plague caused by yersinia pestis manifests itself in bubonic, septicemic, and pneumonic forms. although the u.s. food and drug administration recently approved levofloxacin, there is no approved human vaccine against plague. the capsular antigen f1 and the low-calcium-response v antigen (lcrv) of y. pestis represent excellent vaccine candidates; however, the inability of the immune responses to f1 and lcrv to provide protection against y. pestis f1(-) strains or those which harbor variants of lc ...201323239803

fast identification of yersinia pestis, bacillus anthracis and francisella tularensis based on conventional pcr.rapid and accurate diagnostic tools for detection and identification of y pestis, b. anthracis and f. tularensis are essential for timely initial appropriate treatment of exposed individuals, which will be critical to their survival, as well as for reduction of the public health impact and the spread of the disease. the paper presents application of fast polymerases and fast dry electrophoresis in conventional pcr as an alternative for real-time pcr application for detection and identification o ...201324730142
identification of anziaic acid, a lichen depside from hypotrachyna sp., as a new topoisomerase poison inhibitor.topoisomerase inhibitors are effective for antibacterial and anticancer therapy because they can lead to the accumulation of the intermediate dna cleavage complex formed by the topoisomerase enzymes, which trigger cell death. here we report the application of a novel enzyme-based high-throughput screening assay to identify natural product extracts that can lead to increased accumulation of the dna cleavage complex formed by recombinant yersinia pestis topoisomerase i as part of a larger effort t ...201323593306
managing iron supply during the infection cycle of a flea borne pathogen, bartonella henselae.bartonella are hemotropic bacteria responsible for emerging zoonoses. most bartonella species appear to share a natural cycle that involves an arthropod transmission, followed by exploitation of a mammalian host in which they cause long-lasting intra-erythrocytic bacteremia. persistence in erythrocytes is considered an adaptation to transmission by bloodsucking arthropod vectors and a strategy to obtain heme required for bartonella growth. bartonella genomes do not encode for siderophore biosynt ...201324151576
a high-throughput screen for quorum-sensing inhibitors that target acyl-homoserine lactone synthases.many proteobacteria use n-acyl-homoserine lactone (acyl-hsl) quorum sensing to control specific genes. acyl-hsl synthesis requires unique enzymes that use s-adenosyl methionine as an acyl acceptor and amino acid donor. we developed and executed an enzyme-coupled high-throughput cell-free screen to discover acyl-hsl synthase inhibitors. the three strongest inhibitors were equally active against two different acyl-hsl synthases: burkholderia mallei bmai1 and yersinia pestis yspi. two of these inhi ...201323924613
