    • Cloning of the cytochrome p450 reductase (crtR) gene and its involvement in the astaxanthin biosynthesis ... 
      Alcaíno Gorman, Jennifer; Barahona‑Crisóstomo, Salvador; Carmona, Marisela; Lozano, Carla; Marcoleta, Andrés; Niklitschek, Mauricio; Sepúlveda, Dionisia; Baeza Cancino, Marcelo; Cifuentes Guzmán, Víctor (BIOMED CENTRAL LTD, 2008-10-06)
      Background: The yeast Xanthophyllomyces dendrorhous synthesizes astaxanthin, a carotenoid with high commercial interest. The proposed biosynthetic route in this organism is isopentenylpyrophosphate (IPP) -> geranyleranyl ...
    • Codon usage and codon context bias in Xanthophyllomyces dendrorhous 
      Baeza Cancino, Marcelo; Alcaíno Gorman, Jennifer; Barahona‑Crisóstomo, Salvador; Sepúlveda, Dionisia; Cifuentes Guzmán, Víctor (BioMed Central, 2015)
      Background Synonymous codons are used differentially in organisms from the three domains of life, a phenomenon referred to as codon usage bias. In addition, codon pair bias, particularly in the 3’ codon context, has also ...
    • Genomic organization of the structural genes controlling the astaxanthin biosynthesis pathway of Xanthophyllomyces ... 
      Niklitschek, Mauricio; Alcaíno Gorman, Jennifer; Barahona‑Crisóstomo, Salvador; Sepúlveda, Dionisia; Lozano, Carla; Carmona, Marisela; Marcoleta, Andrés; Martínez, Claudio; Lodato, Patricia; Baeza Cancino, Marcelo; Cifuentes Guzmán, Víctor (Sociedad de Biología de Chile, 2008-05-05)
      The cloning and nucleotide sequence of the genes (idi, crtE, crtYB, crtI and crtS) controlling the astaxanthin biosynthesis pathway of the wild-type ATCC 24230 strain of Xanthophyllomyces dendrorhous in their genomic and ...
    • Identification and analysis of metabolite production with biotechnological potential in Xanthophyllomyces ... 
      Contreras, Gabriela; Barahona‑Crisóstomo, Salvador; Sepúlveda, Dionisia; Baeza Cancino, Marcelo (Springer, 2015)
      Abstract Antarctic microorganisms have developed different strategies to live in their environments, including modifications to their membrane components to regulate fluidity and the production of photoprotective ...
    • Identification and functional characterization of the CYP51 gene from the yeast Xanthophyllomyces dendrorhous ... 
      Leiva, Kritsye; Werner, Nicole; Sepúlveda, Dionisia; Barahona‑Crisóstomo, Salvador; Baeza Cancino, Marcelo; Cifuentes Guzmán, Víctor; Alcaíno Gorman, Jennifer (BioMed Central, 2015)
      Background: Xanthophyllomyces dendrorhous is a basidiomycetous yeast that synthesizes astaxanthin, a carotenoid with great biotechnological impact. The ergosterol and carotenoid synthetic pathways derive from the ...
    • Isolation, characterization and long term preservation of mutant strains of Xanthophyllomyces dendrorhous 
      Baeza Cancino, Marcelo; Retamales Molina, Patricio; Sepúlveda, Dionisia; Lodato, Patricia; Jiménez, Antonio; Cifuentes Guzmán, Víctor (WILEY-V C H VERLAG GMBH, 2008-05-16)
      The yeast Xanthophyllomyces dendrorhous is biotechnologically important due to its ability to produce the pigment astaxanthin, but is poorly understood at the genetic level. This is mainly because its preservation is ...
    • Molecular Characterization and Functional Analysis of Cytochrome b5 Reductase (CBR) Encoding Genes from the ... 
      Gutiérrez, María Soledad; Rojas Garrido, María Cecilia; Sepúlveda, Dionisia; Baeza Cancino, Marcelo; Cifuentes Guzmán, Víctor; Alcaíno Gorman, Jennifer (Public Library Science, 2015)
      The eukaryotic microsomal cytochrome P450 systems consist of a cytochrome P450 enzyme (P450) and a cytochrome P450 redox partner, which generally is a cytochrome P450 reductase (CPR) that supplies electrons from NADPH. ...
    • Role of ROX1, SKN7, and YAP6 stress transcription factors in the production of secondary metabolites in ... 
      Martínez Moya, Pilar; Campusano, Sebastián; Sepúlveda, Dionisia; Paradela Elizalde, Alberto; Alcaíno Gorman, Jennifer Cecilia; Baeza Cancino, Marcelo Enrique; Cifuentes, Víctor (MDPI, 2022)
      Xanthophyllomyces dendrorhous is a natural source of astaxanthin and mycosporines. This yeast has been isolated from high and cold mountainous regions around the world, and the production of these secondary metabolites ...
    • The involvement of mig1 from xanthophyllomyces dendrorhous in catabolic repression: An active mechanism ... 
      Alcaíno Gorman, Jennifer; Bravo, Natalia; Córdova, Pamela; Marcoleta Caldera, Andrés; Contreras, Gabriela; Barahona Crisóstomo, Salvador; Sepúlveda, Dionisia; Fernández Lobato, María; Baeza Cancino, Marcelo; Cifuentes Guzmán, Víctor (Public Library of Science, 2016)
      The red yeast X. dendrorhous is one of the few natural sources of astaxanthin, a carotenoid used in aquaculture for salmonid fish pigmentation and in the cosmetic and pharmaceutical industries for its antioxidant properties. ...
