    • Codon usage revisited: lack of correlation between codon usage and the number of tRNA genes in enterobacteria 
      Rojas, Joaquin; Castillo, Gabriel; Leiva Araya, Lorenzo; Elgamal, Sara; Orellana Orellana, Omar; Ibba, Michael; Katz Zondek, Assaf (Elsevier, 2018-08-25)
      It is widely believed that if a high number of genes are found for any tRNA in a rapidly replicating bacteria, then the cytoplasmic levels of that tRNA will be high and an open reading frame containing a higher frequency ...
    • Coevolution of an aminoacyl-tRNA synthetase with its tRNA substrates 
      Salazar Garrido, Juan; Ahel, Iván; Orellana Orellana, Omar; Tumbula-Hansen, Debra; Krieger, Robert; Daniels, Lacy; Soll, Dieter (NATL ACAD SCIENCES, 2003-11-25)
      Glutamyl-tRNA synthetases (GluRSs) occur in two types, the discriminating and the nondiscriminating enzymes. They differ in their choice of substrates and use either tRNA(Glu) or both tRNA(Glu) and tRNA(Gln). Although most ...
    • Deciphering the role of multiple thioredoxin fold proteins of leptospirillum sp. in oxidative stress tolerance 
      González Aristegui, Daniela; Álamos, Pamela; Rivero, Matías; Orellana Orellana, Omar; Norambuena, Javiera; Chávez, Renato; Levicán, Gloria (MDPI, 2020)
      Thioredoxin fold proteins (TFPs) form a family of diverse proteins involved in thiol/disulfide exchange in cells from all domains of life. Leptospirillum spp. are bioleaching bacteria naturally exposed to extreme conditions ...
    • Microarray and bioinformatic analyses suggest models for carbon metabolism in the autotroph Acidithiobacillus ... 
      Appia Ayme, Corinne; Quatrini, Raquel; Denis, Yann; Denizot, François; Silver, Simon; Roberto, Francisco; Veloso, Felipe A.; Valdés, Jorge; Cárdenas, Juan; Esparza, Mario; Orellana Orellana, Omar; Jedlicki Corbeaux, Eugenia; Bonnefoy, Violaine; Holmes, David S. (ELSEVIER, 2006-09)
      Acidithiobacillus ferrooxidans is a chemolithoautotrophic bacterium that uses iron or sulfur as an energy and electron source. Bioinformatic analysis of the A. ferrooxidans draft genome sequence was used to identify putative ...
    • The type IV secretion system of ICEAfe1: Formation of a conjugative pilus in Acidithiobacillus ferrooxidans 
      Flores Ríos, Rodrigo; Moya Beltrán, Ana; Pareja-Barrueto, Claudia; Arenas-Salinas, Mauricio; Valenzuela, I. Sebastián; Orellana Orellana, Omar; Quatrini, Raquel (Frontiers Media S.A., 2019)
      Copyright © 2019 Flores-Ríos, Moya-Beltrán, Pareja-Barrueto, Arenas-Salinas, Valenzuela, Orellana and Quatrini.The dispersal of mobile genetic elements and their gene cargo relies on type IV secretion systems (T4SS). In ...
    • Type IV secretion systems diversity in the Acidithiobacillus genus 
      Flores Ríos, Rodrigo; Moya Beltrán, Ana; Covarrubias, Paulo C.; Acuña, Lillian G.; Orellana Orellana, Omar; Quatrini, Raquel (Trans Tech Publications, 2017)
      Dispersal between genomes of certain mobile genetic elements and their gene cargo depends on conjugative type IV secretion systems. In this work, variants of these nanomachines, tra and trb, have been profiled in publicly ...
