Laboratoř strukturní bioinformatiky proteinů

Strukturní a funkční vlastnosti biologicky významných molekul a jejich interakcí pomocí nástrojů strukturní bioinformatiky a molekulového modelování.

Vedoucí laboratoře: Ing. Jiří Černý, Ph.D.

Výzkum se soustředí na pochopení strukturních a funkčních vlastností biologicky významných molekul a jejich interakcí pomocí nástrojů strukturní bioinformatiky a molekulového modelování. V rámci BTÚ a BIOCEV spolupracujeme zejména na analýze strukturních dat, návrhu proteinových mutací a návrhu ligandů a inhibitorů studovaných proteinů.

  Studované systémy

  • Analýza konformačního chování oligopeptidových bloků v proteinech.
  • Návrh stabilních proteinových scaffoldů vhodných pro mutagenezi.
  • Identifikace proteinových residuí klíčových pro rozpoznávání a sílu interakcí.
  • Vývoj a testování výpočetních metod a postupů pro modelování struktury a vlastností biomolekul a jejich komplexů.
  • Vývoj nových výpočetních metod a parametrů pro popis vlastností a interakcí navržených ligandů a inhibitorů.

  Metody

  • Homologní modelování.
  • Molekulová dynamika (MD).
  • Ab initio kvantově chemické výpočty.
  • In silico mutageneze.
  • Dokování protein/protein a ligand/protein.
