Availability for Thesis Projects
Disponibili due posti di internato di Tesi di Laurea Magistrale per studenti di CTF, Farmacia e Pharmaceutical Biotechnologies da MARZO 2023. Il progetto di Tesi verterà sullo studio della conformazione e dinamica di proteine allo scopo di chiarire variazioni conformazionali che causano determinati stati patologici. Le tecniche utilizzate nel progetto riguarderanno la caratterizzazione chimica delle proteine mediante RP-HPLC e spettrometria di massa e la caratterizzazione conformazionale di proteine mediante tecnica di scambio idrogeno-deuterio e spettrometria di massa e mediante tecniche spettroscopiche (dicroismo circolare e fluorescenza).
Research
Scientific Activities
During the PhD and the post-doctoral period, I worked on the conformational characterization of proteins by means of spectroscopic techniques and by combining limited proteolysis and mass spectrometry. Our group studied the conformational changes determined on model proteins and on proteins of pharmaceutical interest by particular solvent conditions and by the interaction with ligands or fatty acids.
My scientific interests are still in the field of the chemical and conformational characterization of proteins, mainly by exploiting mass spectrometry techniques. Recently, I focused on microbial transglutaminase (TGase), an enzyme that allows the site-specific derivatization of proteins at the level of Lys or Gln residues often without affecting protein structure and function. We investigated if the conformational features of the protein substrate determine the sites of TGase derivatization and we used this enzyme to modify proteins with fluorophores, chelating agents or other compounds to enable a range of biotechnological applications.
Currently, we are implenting the hydrogen-deuterium eschange mass spectrometry technique (HDX-MS) that allows mapping of protein conformation in solution under physiological conditions using small amounts of material. We apply this methodology on different protein systems of physio-pathological relevance, that are under study in our laboratory or in on-going collaborations.
