role of ser11 in the stabilization of the structure of ochrobactrum anthropi glutathione transferase.gsts (glutathione transferases) are a multifunctional group of enzymes, widely distributed and involved in cellular detoxification processes. in the xenobiotic-degrading bacterium ochrobactrum anthropi, gst is overexpressed in the presence of toxic concentrations of aromatic compounds such as 4-chlorophenol and atrazine. we have determined the crystal structure of the gst from o. anthropi (oagst) in complex with gsh. like other bacterial gsts, oagst belongs to the beta class and shows a similar ...200717223798
the first structure of a cold-active catalase from vibrio salmonicida at 1.96 a reveals structural aspects of cold adaptation.the cold-adapted catalase from the fish-pathogenic bacterium vibrio salmonicida (vsc) has recently been characterized and shown to be two times more catalytically efficient compared with catalase from the mesophilic human pathogen proteus mirabilis [pmc; lorentzen et al. (2006), extremophiles, 10, 427-440]. vsc is also less temperature-stable, with a half-life of 5 min at 333 k compared with 50 min for pmc. this was the background for solving the crystal structure of the cold-adapted vsc to 1.96 ...200717242507

regulation of flhdc expression in proteus mirabilis.transposon insertions located 325 and 740 base pairs upstream of the transcriptional start site of the flhdc operon resulted in cells that initiated swarming 1.5h earlier than wild-type and exhibited a 2-2.5-fold greater swarming velocity. these mutants also failed to consolidate (de-differentiate) normally and did not form the characteristic bulls-eye pattern of concentric swarming rings on solid media. the analysis of one mutant (ss-p) with an insertion at -325 revealed that the levels of flhd ...200717320355
evaluating antibiotics for use in medicine using a poloxamer biofilm model.wound infections, due to biofilms, are a constant problem because of their recalcitrant nature towards antibiotics. appropriate antibiotic selection for the treatment of these biofilm infections is important. the traditional in vitro disc diffusion method for antibiotic selection uses bacterial cultures grown on agar plates. however, the form of bacterial growth on agar is not representative of how bacteria grow in wounds and other tissue sites as here bacteria grow naturally in a biofilm. the a ...200717302978
the xaxab genes encoding a new apoptotic toxin from the insect pathogen xenorhabdus nematophila are present in plant and human pathogens.xenorhabdus nematophila, a member of the enterobacteriaceae, kills many species of insects by strongly depressing the immune system and colonizing the entire body. a peptide cytotoxin has been purified from x. nematophila broth growth, and the cytolytic effect on insect immunocytes and hemolytic effect on mammalian red blood cells of this toxin have been described (ribeiro, c., vignes, m., and brehélin, m.

the effect of lipopolysaccharide from proteus mirabilis on the level of the stable end metabolic products of nitric oxide in blood platelets.nitric oxide ((*)no) plays an important role in a number of physiologic processes. evidence exists that (*)no, which stimulates soluble guanylate cyclase and enhances cyclic guanosine monophosphate (cgmp) levels, may inhibit platelet activation. in contrast, during platelet activation induced by different agonists, synthesis of (*)no in platelets occurs. in these studies, production of the stable end-products of (*)no-nitrite and nitrate (no(x)) in human platelets, stimulated by different doses ...200717160361
