    Article
    Open Access
    Oxidation of primary alcohols by aryl-alcohol oxidase (AAO), a flavoenzyme that provides H2O2 to fungal peroxidases for lignin degradation in nature, is achieved by concerted hydroxyl proton transfer and stereoselective ...

  • Selective synthesis of 4-hydroxyisophorone and 4-ketoisophorone by fungal peroxygenases 

    Aranda, Carmen; Municoy, Martí; Guallar, Victor; Kiebist, Jan; Scheibner, Katrin; Ullrich, René; del Río, José C.; Hofrichter, Martin; Martinez, Angel T.; Gutierrez, Ana (Royal Society of Chemistry, 2019-02-26)
    Article
    Open Access
    The recently discovered unspecific peroxygenases (UPOs) from the ascomycetes Chaetomium globosum and Humicola insolens were capable of selectively hydroxylating isophorone to 4-hydroxyisophorone (4HIP) and 4-ketoisophorone ...

  • SKEMPI 2.0: an updated benchmark of changes in protein–protein binding energy, kinetics and thermodynamics upon mutation 

    Jankauskaite, Justina; Jiménez-García, Brian; Dapkunas, Justas; Fernández-Recio, Juan; Moal, Iain H. (Oxford University Press, 2018-07-18)
    Article
    Open Access
    Motivation: Understanding the relationship between the sequence, structure, binding energy, binding kinetics and binding thermodynamics of protein–protein interactions is crucial to understanding cellular signaling, the ...

  • Multitrait genome association analysis identifies new susceptibility genes for human anthropometric variation in the GCAT cohort 

    Galván Femenía, Iván; Obón-Santacana, Mireia; Piñeyro, David; Guindo-Martinez, Marta; Duran, Xavier; Carreras, Anna; Pluvinet, Raquel; Velasco, Juan; Ramos, Laia; Aussó, Susanna; Puig, Lluis; Perucho, Manuel; Torrents, David; Moreno, Victor; Sumoy, Lauro; de Cid, Rafael (BMJ Publishing Group, 2018-08-30)
    Article
    Open Access
    Background Heritability estimates have revealed an important contribution of SNP variants for most common traits; however, SNP analysis by single-trait genome-wide association studies (GWAS) has failed to uncover their ...

  • Description of a Non-Canonical Mn(II)-Oxidation Site in Peroxidases 

    Fernández-Fueyo, Elena; Davó-Siguero, Irene; Almendral, David; Linde, Dolores; Baratto, Maria C.; Pogni, Rebecca; Romero, Antonio; Guallar, Victor; Martinez, Angel T. (American Chemical Society, 2018-07-31)
    Article
    Open Access
    A dye-decolorizing peroxidase (DyP) from Pleurotus ostreatus (PosDyP4) catalyzes the oxidation of Mn2+ to Mn3+, in the presence of H2O2, with an efficiency similar to the well-known manganese peroxidases and versatile ...

  • Pushing the Limits of Computational Structure-Based Drug Design with a Cryo-EM Structure: The Ca2+ Channel α2δ-1 Subunit as a Test Case

    Article
    Open Access
    Cryo-electron microscopy (cryo-EM) is emerging as a real alternative for structural elucidation. In spite of this, very few cryo-EM structures have been described so far as successful platforms for in silico drug design. ...

  • Intrinsically active MEK variants are differentially regulated by proteinases and phosphatases
