El grup de recerca treballa en el camp de l'estructura-funció de proteïnes d'interès biomèdic i biotecnològic. Es porta a terme el disseny i l?obtenció de proteïnes recombinants mitjançant tècniques d'enginyeria genètica. Aquestes proteïnes són purificades i caracteritzades per tècniques bioquímiques i espectroscòpiques. També es treballa en la modificació d'enzims per a aplicacions en processos biotecnològics d'interès industrial.

The research group works on the structure and function of proteins of biomedical and biotechnological relevance. Recombinant proteins are designed and obtained by means of genetic engineering techniques. These proteins are purified and characterised using biochemical and spectroscopic methods. Enzyme engineering and modification are also studied, for their application to biotechnological processes in industry.

    Contact lenses (CL) provide visual correction but their use may also induce several adverse effects causative of discomfort and conditions that lead to stop or discontinue their use. Discomfort is mainly caused by insufficient ...
  • Molecular features characterizing non-peptide selectivity to the human B1 and B2 bradykinin receptors 

    Rasaeifar, B.; Lupala, C.S.; Gómez Gutierrez, Patricia; Pérez González, Juan Jesús (2019-01-01)
    Article
    Restricted access - publisher's policy
    Bradykinin is produced in response to inflammation, trauma, burns, shock, allergy and some cardiovascular diseases. Actions of this peptide are mediated through two different G-protein coupled receptors, named B1 and B2 ...
  • Physical states and thermodynamic properties of model Gram-negative bacterial inner membranes 

    Hoyo Pérez, Javier; Torrent Burgués, Juan; Tzanov, Tzanko (2018-12-06)
    Article
    Restricted access - publisher's policy
    Novel antimicrobial agents are focused to interact with the bacterial membrane whose lipid composition (number and position of unsaturations and lipid headgroup) is adapted according to environmental signals. The anticipation ...
  • Metal-enzyme nanoaggregates eradicate both gram-positive and gram-negative bacteria and their biofilms 

    Ferreres Cabanes, Guillem; Bassegoda Puigdomenech, Arnau; Hoyo Pérez, Javier; Torrent Burgués, Juan; Tzanov, Tzanko (2018-11-13)
    Article
    Restricted access - publisher's policy
    To palliate the appearance of antimicrobial resistance (AMR), the use of bactericidal agents acting differently than conventional antibiotics and the elimination of bacterial biofilm, are the two most promising strategies. ...
  • Smart sensing fabrics for live bacteria detection 

    Ferrer-Vilanova, Amparo; Ivanova, Kristina Dimitrova; Diaz-Gonzalez, Maria; Alonso, Yasmine; Guirado, Gonzalo; Tzanov, Tzanko; Muños-Berbel, Xavier (Multidisciplinary Digital Publishing Institute (MDPI), 2018-11-27)
    Article
    Open Access
    A smart textile for live bacteria detection of antimicrobial hospital tissues is here proposed. The capacity to detect viable bacteria is based on the use of Prussian Blue (PB) as electrochromic compound, with a clear ...
  • Enzymatic synthesis of a thiolated chitosan-based wound dressing crosslinked with chicoric acid 

    Stefanov, Ivaylo; Hinojosa Caballero, Dolores; Maspoch, Santiago; Hoyo Pérez, Javier; Tzanov, Tzanko (Royal Society of Chemistry (RSC), 2018-10-26)
    Article
    Open Access
    This work describes the enzymatic synthesis of multifunctional hydrogels for chronic wound treatment using thiolated chitosan and the natural polyphenol chicoric acid. Gelation was achieved by ...
