Dissimilation of Cysteate Via 3-Sulfolactate Sulfo-Lyase and a Sulfate Exporter in Paracoccus Pantotrophus NKNCYSA
Microbiology (2005), 151, 737–747 DOI 10.1099/mic.0.27548-0 Dissimilation of cysteate via 3-sulfolactate sulfo-lyase and a sulfate exporter in Paracoccus pantotrophus NKNCYSA Ulrike Rein,1 Ronnie Gueta,1 Karin Denger,1 Ju¨rgen Ruff,1 Klaus Hollemeyer2 and Alasdair M. Cook1 Correspondence 1Department of Biology, The University, D-78457 Konstanz, Germany Alasdair Cook 2Institute of Biochemical Engineering, Saarland University, Box 50 11 50, D-66041 [email protected] Saarbru¨cken, Germany Paracoccus pantotrophus NKNCYSA utilizes (R)-cysteate (2-amino-3-sulfopropionate) as a sole source of carbon and energy for growth, with either nitrate or molecular oxygen as terminal electron acceptor, and the specific utilization rate of cysteate is about 2 mkat (kg protein)”1. The initial degradative reaction is catalysed by an (R)-cysteate : 2-oxoglutarate aminotransferase, which yields 3-sulfopyruvate. The latter was reduced to 3-sulfolactate by an NAD-linked sulfolactate dehydrogenase [3?3 mkat (kg protein)”1]. The inducible desulfonation reaction was not detected initially in cell extracts. However, a strongly induced protein with subunits of 8 kDa (a) and 42 kDa (b) was found and purified. The corresponding genes had similarities to those encoding altronate dehydratases, which often require iron for activity. The purified enzyme could then be shown to convert 3-sulfolactate to sulfite and pyruvate and it was termed sulfolactate sulfo-lyase (Suy). A high level of sulfite dehydrogenase was also induced during growth with cysteate, and the organism excreted sulfate. A putative regulator, OrfR, was encoded upstream of suyAB on the reverse strand. Downstream of suyAB was suyZ, which was cotranscribed with suyB. -
Novel Non-Phosphorylative Pathway of Pentose Metabolism from Bacteria
www.nature.com/scientificreports OPEN Novel non-phosphorylative pathway of pentose metabolism from bacteria Received: 22 March 2018 Seiya Watanabe1,2,3, Fumiyasu Fukumori4, Hisashi Nishiwaki1,2, Yasuhiro Sakurai5, Accepted: 30 September 2018 Kunihiko Tajima5 & Yasuo Watanabe1,2 Published: xx xx xxxx Pentoses, including D-xylose, L-arabinose, and D-arabinose, are generally phosphorylated to D-xylulose 5-phosphate in bacteria and fungi. However, in non-phosphorylative pathways analogous to the Entner-Dodorof pathway in bacteria and archaea, such pentoses can be converted to pyruvate and glycolaldehyde (Route I) or α-ketoglutarate (Route II) via a 2-keto-3-deoxypentonate (KDP) intermediate. Putative gene clusters related to these metabolic pathways were identifed on the genome of Herbaspirillum huttiense IAM 15032 using a bioinformatic analysis. The biochemical characterization of C785_RS13685, one of the components encoded to D-arabinonate dehydratase, difered from the known acid-sugar dehydratases. The biochemical characterization of the remaining components and a genetic expression analysis revealed that D- and L-KDP were converted not only to α-ketoglutarate, but also pyruvate and glycolate through the participation of dehydrogenase and hydrolase (Route III). Further analyses revealed that the Route II pathway of D-arabinose metabolism was not evolutionally related to the analogous pathway from archaea. Te breakdown of D-glucose is central for energy and biosynthetic metabolism throughout all domains of life. Te most common glycolytic routes in bacteria are the Embden-Meyerhof-Parnas, the Entner-Doudorof (ED), and the oxidative pentose phosphate pathways. Te distinguishing diference between the two former glyco- lytic pathways lies in the nature of the 6-carbon metabolic intermediates that serve as substrates for aldol cleav- age. -
Within-Host Diversity of Multidrug-Resistant Escherichia Coli in the Gut and Bladder Sofiya G. Shevchenko a Dissertation Submitt
Within-host Diversity of Multidrug-Resistant Escherichia coli in the Gut and Bladder Sofiya G. Shevchenko A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2019 Reading committee: Evgeni Sokurenko, Chair John Mittler Kevin Hybiske Program Authorized to Offer Degree: Microbiology ©Copyright 2019 Sofiya G. Shevchenko University of Washington Abstract Within-host Diversity of Escherichia coli in the Gut and Bladder Sofiya G. Shevchenko Chair of the Supervisory Committee: Evgeni V. Sokurenko Department of Microbiology Uropathogenic E. coli are paradoxically able to both cause disease in the urinary tract, and reside there asymptomatically. The pandemic, multi-drug resistant E. coli subclone ST131-H30 (H30) is of special interest, as it has been found to persist in the gut and bladder of healthy people. In order to understand this persistence, we investigated whether H30 is competitive in these niches and thus able to persist by excluding other E. coli, as well as whether H30 may persist via within-host adaptation. In order to assess the E. coli clonal landscape, we developed a novel method based on deep sequencing of two loci, along with an algorithm for analysis of resulting data. Using this method, we assessed fecal and urinary samples from healthy women carrying H30, and found that even in the absence of antibiotic use, H30 could completely dominate the gut and, especially, urine of healthy carriers. In order to ascertain whether H30 adapts within- host, we employed population-level whole genome sequencing, and determined that H30 undergoes changes in genes affecting respiration in the gut, similar to commensal gut E. -

Regulatory Role of Plar (Yiaj) for Plant Utilization in Escherichia Coli K-12
www.nature.com/scientificreports Corrected: Author Correction OPEN Regulatory Role of PlaR (YiaJ) for Plant Utilization in Escherichia coli K-12 Tomohiro Shimada 1,2*, Yui Yokoyama3, Takumi Anzai1, Kaneyoshi Yamamoto3 & Akira Ishihama2,3* Outside a warm-blooded animal host, the enterobacterium Escherichia coli K-12 is also able to grow and survive in stressful nature. The major organic substance in nature is plant, but the genetic system of E. coli how to utilize plant-derived materials as nutrients is poorly understood. Here we describe the set of regulatory targets for uncharacterized IclR-family transcription factor YiaJ on the E. coli genome, using gSELEX screening system. Among a total of 18 high-afnity binding targets of YiaJ, the major regulatory target was identifed to be the yiaLMNOPQRS operon for utilization of ascorbate from fruits and galacturonate from plant pectin. The targets of YiaJ also include the genes involved in the utilization for other plant-derived materials as nutrients such as fructose, sorbitol, glycerol and fructoselysine. Detailed in vitro and in vivo analyses suggest that L-ascorbate and α-D-galacturonate are the efector ligands for regulation of YiaJ function. These fndings altogether indicate that YiaJ plays a major regulatory role in expression of a set of the genes for the utilization of plant-derived materials as nutrients for survival. PlaR was also suggested to play protecting roles of E. coli under stressful environments in nature, including the formation of bioflm. We then propose renaming YiaJ to PlaR (regulator of plant utilization). Bacteria constantly monitor environmental conditions, and respond for adaptation and survival by modulating the expression pattern of their genomes. -
