    • Apparent redundancy of electron transfer pathways via bc(1) complexes and terminal oxidases in the extremophilic ... 
      Brasseur, G.; Levicán, Gloria; Bonnefoy, Violaine; Holmes, David S.; Jedlicki Corbeaux, Eugenia; Lemesle Meunier, D. (ELSEVIER, 2004-06-07)
      Acidithiobacillus ferrooxidans is an acidophilic chemolithoautotrophic bacterium that can grow in the presence of either the weak reductant Fe2+, or reducing sulfur compounds that provide more energy for growth than Fe2+. ...
    • Cellular levels of heme affect the activity of dimeric glutamyl-tRNA reductase 
      Armas-Ricard, Merly de; Levicán, Gloria; Katz, Assaf; Moser, Jurgen; Jahn, Dieter; Orellana Orellana, Omar (Elsevier, 2011-02-04)
      Glutamyl-tRNA reductase (GluTR) is the first enzyme committed to tetrapyrrole biosynthesis by the C(5)-pathway. This enzyme transforms glutamyl-tRNA into glutamate-1-semi-aldehyde, which is then transformed into 5-amino ...
    • Comparative genomic analysis of carbon and nitrogen assimilation mechanisms in three indigenous bioleaching ... 
      Levicán, Gloria; Ugalde, Juan A.; Ehrenfeld, Nicole; Maass Sepúlveda, Alejandro; Parada, Pilar (BIOMED CENTRAL LTD, CURRENT SCIENCE GROUP, 2008-12-03)
      Background: Carbon and nitrogen fixation are essential pathways for autotrophic bacteria living in extreme environments. These bacteria can use carbon dioxide directly from the air as their sole carbon source and can use ...
    • Cultivable psychrotolerant yeasts associated with Antarctic marine sponges 
      Vaca Cerezo, Inmaculada; Faúndez, Carolina; Maza, Felipe; Paillavil, Braulio; Hernández, Valentina; Acosta, Fermín; Levicán, Gloria; Martínez, Claudio; Chávez, Renato (Springer, 2013)
      Unlike filamentous fungi and bacteria, very little is known about cultivable yeasts associated with marine sponges, especially those from Antarctic seas. During an expedition to King George Island, in the Antarctica, samples ...
    • Glucose-induced production of a Penicillium purpurogenum xylanase by Aspergillus nidulans 
      Ravanal, María Cristina; Espinosa, Yeison; Rosa, Lorena; Vaca Cerezo, Inmaculada; Polanco, Rubén; Eyzaguirre, Jaime; Levicán, Gloria; Chávez, Renato (Springer, 2012)
      The heterologous secretion of xylanase B from Penicillium purpurogenum using glucose as inducer was performed in Aspergillus nidulans. For this purpose, plasmid pEVXB, containing the xylanase B cDNA (including its own ...
    • Identification and Functional Analysis of the Mycophenolic Acid Gene Cluster of Penicillium roqueforti 
      Cid, Abdiel del; Gil Durán, Carlos; Vaca Cerezo, Inmaculada; Rojas Aedo, Juan F.; García Rico, Ramón O.; Levicán, Gloria; Chávez, Renato (Public Library Science, 2016)
      The filamentous fungus Penicillium roqueforti is widely known as the ripening agent of blue-veined cheeses. Additionally, this fungus is able to produce several secondary metabolites, including the meroterpenoid compound ...
    • IMA genome-F14 draft genome sequences of penicillium roqueforti, fusarium sororula, chrysoporthe puriensis, ... 
      Van der Nest, Magriet A.; Chávez, Renato; De Vos, Lieschen; Duong, Tuan A.; Gil Durán, Carlos; Ferreira, María Alves; Lane, Frances a.; Levicán, Gloria; Santana, Quentin C.; Steenkamp, Emma T.; Suzuki, Hiroyuki; Tello, Mario; Rakoma, Jostina R.; Vaca Cerezo, Inmaculada; Valdés, Natalia; Wilken, P. Markus; Wingfield, Michael J.; Wingfield, Brenda D. (BMC, 2021)
      Draft genomes of Penicillium roqueforti, Fusarium sororula, Chalaropsis populi, and Chrysoporthe puriensis are presented. Penicillium roqueforti is a model fungus for genetics, physiological and metabolic studies, as well ...
    • The pcz1 Gene, which Encodes a Zn(II)(2)Cys(6) Protein, Is Involved in the Control of Growth, Conidiation, ... 
      Gil Durán, Carlos; Rojas Aedo, Juan F.; Medina, Exequiel; Vaca Cerezo, Inmaculada; García Rico, Ramón O.; Villagrán, Sebastián; Levicán, Gloria; Chávez, Renato (Public Library Science, 2015)
      Proteins containing Zn(II)(2)Cys(6) domains are exclusively found in fungi and yeasts. Genes encoding this class of proteins are broadly distributed in fungi, but few of them have been functionally characterized. In this ...
    • The emergence of new catalytic abilities in an endoxylanase from family GH10 by removing an intrinsically ... 
      Gil Durán, Carlos; Sepúlveda, Romina V.; Rojas, Maximiliano; Castro Fernández, Víctor Hugo; Guixe Leguia, Victoria; Vaca Cerezo, Inmaculada; Levicán, Gloria; González Nilo, Fernando; Ravanal, María Cristina; Chávez, Renato (MDPI, 2022)
      Endoxylanases belonging to family 10 of the glycoside hydrolases (GH10) are versatile in the use of different substrates. Thus, an understanding of the molecular mechanisms underlying substrate specificities could be very ...
    • The pcz1 Gene, which Encodes a Zn(II)2Cys6 Protein, Is Involved in the Control of Growth, Conidiation, ...
