    DISSERTATION FOLATE PATHWAY INHIBITOR RESISTANCE MECHANISMS IN BURKHOLDERIA PSEUDOMALLEI Submitted by Nicole L. Podnecky Department of Microbiology, Immunology and Pathology In partial fulfillment of the requirements For the Degree of Doctor of Philosophy Colorado State University Fort Collins, Colorado Fall 2013 Doctoral Committee: Advisor: Herbert P. Schweizer Steven W. Dow Richard A. Slayden Laurie A. Stargell ABSTRACT FOLATE PATHWAY INHIBITOR RESISTANCE MECHANISMS IN BURKHOLDERIA PSEUDOMALLEI Antimicrobials are invaluable tools used to facilitate the treatment of infectious diseases. Their use has saved millions of lives since their introduction in the early 1900’s. Unfortunately, due to the increased incidence and dispersal of antimicrobial resistance determinants, many of these drugs are no longer efficacious. This greatly limits the options available for treatment of serious bacterial infections, including melioidosis, which is caused by Burkholderia pseudomallei, a Gram-negative saprophyte. This organism is intrinsically resistant to many antimicrobials. Additionally, there have been reports of B. pseudomallei isolates resistant to several of the antimicrobials currently used for treatment, including the trimethoprim and sulfamethoxazole combination, co-trimoxazole. The overarching goal of this project was to identify and characterize mechanisms of trimethoprim and sulfamethoxazole resistance in clinical and environmental isolates, as well as in laboratory induced mutants. Prior to these studies, very little work has been done to identify and characterize the mechanisms by which B. pseudomallei strains are or could become resistant to folate-pathway inhibitors, specifically trimethoprim and sulfamethoxazole. During the initial phases of these studies, we determined the antimicrobial susceptibilities of a large collection of clinical and environmental isolates from Thailand and Australia (n = 65).

  • Bacterial Oxidases of the Cytochrome Bd Family: Redox Enzymes of Unique Structure, Function, and Utility As Drug Targets
    Published in "Antioxidants & Redox Signaling doi: 10.1089/ars.2020.8039, 2020" which should be cited to refer to this work. Bacterial Oxidases of the Cytochrome bd Family: Redox Enzymes of Unique Structure, Function, and Utility As Drug Targets Vitaliy B. Borisov,1 Sergey A. Siletsky,1 Alessandro Paiardini,2 David Hoogewijs,3 Elena Forte,2 Alessandro Giuffre`,4 and Robert K. Poole5 Abstract Significance: Cytochrome bd is a ubiquinol:oxygen oxidoreductase of many prokaryotic respiratory chains with a unique structure and functional characteristics. Its primary role is to couple the reduction of molecular oxygen, even at submicromolar concentrations, to water with the generation of a proton motive force used for adenosine triphosphate production. Cytochrome bd is found in many bacterial pathogens and, surprisingly, in bacteria for- mally denoted as anaerobes. It endows bacteria with resistance to various stressors and is a potential drug target. Recent Advances: We summarize recent advances in the biochemistry, structure, and physiological functions of cytochrome bd in the light of exciting new three-dimensional structures of the oxidase. The newly discovered roles of cytochrome bd in contributing to bacterial protection against hydrogen peroxide, nitric oxide, perox- ynitrite, and hydrogen sulfide are assessed. Critical Issues: Fundamental questions remain regarding the precise delineation of electron flow within this multihaem oxidase and how the extraordinarily high affinity for oxygen is accomplished, while endowing bacteria with resistance to other small ligands. Future Directions: It is clear that cytochrome bd is unique in its ability to confer resistance to toxic small molecules, a property that is significant for understanding the propensity of pathogens to possess this oxidase.

For both of these uses, a transposon with minimal insertion bias is desired to allow complete coverage with minimal oversampling. Findings: Three transposons, Mu, Tn5, and Tn7, were used to generate insertions in the same set of fosmids containing Candida glabrata genomic DNA.

I would like to thank my committee members Dr. Howard Judelson and Dr. Julia Bailey-Serres for all of their guidance and valuable input that has enhanced the quality of my dissertation research. I would also like to thank my undergraduate advisor Dr. Martin Case who taught me how to write scientifically. Members of the Atkinson lab have become a family for me – one of them literally. I met my wife and the love of my life, Jennifer Wright, in the Atkinson lab. She has been a rock for me, providing me with love and support in so many ways. I feel blessed to have her my life. I would not be the scientist that I am with out Rob Hice. He has taught me more about science than anyone else in my academic career and I am thankful to have him in my life as both a teacher and a friend.

  • Distribution of Cytochromes in Bacteria: Relationship to General Physiology DAVID J
    INTERNATIONAL JOURNAL of SYSTEMATIC BACTERIOLOGY Vol. 23, No. 4 October 1973, p. 459-467 Prin ted in U.S.A. Copyright 0 1973 International Association of Microbiological Societies Distribution of Cytochromes in Bacteria: Relationship to General Physiology DAVID J. MEYER' and COLIN W. JONES Department of Biochemistry, The University of Leicester, England A review of cytochrome occurrence in bacteria is presented which gives the taxonomic distribution of cytochromes and which relates this to general physiological characteristics. Data obtained from published research and recent experimental studies on a total of 169 species of bacteria suggested the existence of four major groupings: (i) the aerobic and facultatively anaerobic, heterotrophic gram positives (cytochrome pattern aa3.0. b.c); (ii) the aerobic and facultatively anaerobic, heterotrophic gram negatives (cytochrome pattern either al.d.o.b.c, a1.o.b.c or aa3.o.b.c); (iii) anaerobic and microaerophilic hetero- trophs (cytochrome pattern b sometimes with al /d/o), and (iv) the ch'emo- and photo-autotrophs (cytochrome pattern c plus czl /aa3/o/b). The absence or minor presence of cytochrome c in facultatively anaerobic and anaerobic heterotrophs was confirmed and was also observed in plant and animal pathogens. Cytochrome d was confined in occurrence mainly to a small taxonomic group of organisms characterized by a high degree of adaptability to unstable habitats. This group was considered for further subdivision dependent upon the conditions causing the production of cytochrome d. As part of an investigation into the occur- ilated on organisms in the three major bacterial orders: rence of more than one spectral type of (i) the taxonomic status of the species according to cytochrome oxidase in many bacteria, a survey Bergey 's Manual of Determinative Bacteriology (13) of published data was carried out.

  • Current Understanding on Cytochrome Bd Quinol Oxidase of Escherichia Coli a Mutagenesis, Kinetics and Spectroscopic Study by Ke
    CURRENT UNDERSTANDING ON CYTOCHROME BD QUINOL OXIDASE OF ESCHERICHIA COLI A MUTAGENESIS, KINETICS AND SPECTROSCOPIC STUDY BY KE YANG DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Biochemistry in the Graduate College of the University of Illinois at Urbana-Champaign, 2009 Urbana, Illinois Doctoral Committee: Professor Robert B. Gennis, Chair Professor Robert B. Gennis, Director of Research Professor Deborah E. Leckband Associate Professor Satish K. Nair Assistant Professor Maria Spies ABSTRACT Time-resolved kinetics study on the cytochrome bd quinol oxidase from Escherichia coli was carried out by stopped-flow techniques. The natural substrate, ubiquinol, was used to turnover the enzyme in the fast catalysis successfully for the first time. The results excluded the fully oxidized form of the enzyme from the rapid catalytic cycle of cytochrome bd oxidase. A re-investigation by both Flow-Flash and EPR on the previously reported mutant at Glu445 in subunit I, uncovered the dithionite-resistant ferric heme b595. Electrometrics data further suggested a series of protonatable groups forming a proton channel located in the membrane to facilitate the proton translocation from cytoplasm to the heme b595 / heme d binuclear center. With help of the increasing database of available cytochrome bd oxidase sequences, site-directed mutagenesis studies were carried out on the highly conserved residues of the enzyme. Mutations on two highly conserved acidic residues in subunit I – Glu99 and Glu107 were characterized in detail. The glutamine substitution at Glu107 was managed to obtain the FTIR redox difference spectra regarding its relatively intact binuclear center. Glu107 was shown to be protonated at pH 7.6 and that it was perturbed by the reduction of the heme b595 / heme d binuclear center at the active site.
