1. Quantum chemical modeling of enzymatic reactions : applications to the tautomerase superfamily
Abstract : In this thesis, quantum chemical methods are used to investigate enzymatic reaction mechanisms. The Density functional theory, in particular the hybrid B3LYP functional, is used to model two enzymes belonging to the tautomerase superfamily; 4-Oxalocrotonate Tautomerase (4-OT) and cis-Chloroacrylic Acid Dehalogenase (cis-CAAD).

2. Gene regulation by different proteins of TGFβ superfamily
Abstract : The present thesis discusses how gene regulation by transforming growth factor β (TGFβ) family cytokines is affected by post-translational modifications of different transcription factors. The thesis also focuses on gene regulation by transcription factors involved in TGFβ signaling. READ MORE

3. Computational exploration of the medium-chain dehydrogenase/reductase superfamily
Abstract : The medium-chain dehydrogenase/reductase (MDR) superfamily is a protein family with more than 170,000 members across all phylogenetic branches. In humans there are 18 representatives. READ MORE

4. Molecular characterization and evolution of alpha-actinin : from protozoa to vertebrates
Abstract : alpha-actinin is a ubiquitous protein found in most eukaryotic organisms. The ability to form dimers allows alpha-actinin to cross-link actin in different structures. In muscle cells alpha-actinin is found at the Z-disk of sarcomeres. READ MORE

5. Cell signaling by Rho and Miro GTPases : Studies of Rho GTPases in Cytoskeletal Reorganizations and of Miro GTPases in Mitochondrial Dynamics
Abstract : The Ras superfamily of GTPases embraces six major branches of proteins: the Ras, Rab, Ran, Arf, Rho and Miro subfamilies. The majority of GTPases function as binary switches that cycle between active GTP-bound and inactive GDP-bound states. This thesis will focus primarily on the biological functions of the Rho and Miro proteins. READ MORE
