Zakład Biologii Strukturalnej

PROFIL

Pracownia koncentruje się na badaniu struktury, funkcji oraz mechanizmów działania kompleksów nukleoproteinowych związanych z podstawowymi procesami replikacji i naprawy DNA. Badamy szereg systemów w komórkach wirusów, bakterii i człowieka, w celu poznania fundamentalnych zasad na temat tworzenia kompleksów makromolekularnych oraz wykorzystania tej wiedzy w możliwych strategiach terapeutycznych.
