A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

© Structural Dynamics Of Macromolecules
The structure of a bacterial analog of the nicotinic receptor (one color per subunit) inserted into the cell membrane (grey and orange). A representation of the volume accessible to ions is shown in yellow.

About

  • We use biophysical experimental techniques such as crystallography and SAXS to visualize at the atomic level the structure of molecules essential to life, such as DNA polymerases involved in DNA Repair and Cancer and ion channels involved in electric nerve signalling.
  • We complement them with molecular and normal modes dynamics, so as to go beyond the essentially static pictures given by these methods.
  • We also try to better understand the electrostatics of macromolecules and their interaction with the solvent, in order to be able to predict their binding properties.
  • Our main goal is to design structure-inspired drugs (pharmacology) and re-design active site(s) to make them accept other substrates (synthetic biology).

Development of methods in computational structural biology

Development of methods in computational structural biology (PI)

We are developing new computational methods to calculate the electrostatics of proteins, understand their dynamical properties and simulate transitions between two known conformations of the same macromolecule.

DNA Replication and Synthetic Biology

DNA Replication and Synthetic Biology (PI)

We work with archaeal DNA polymerases to make them accept xeno-nucleotides and synthesize variants of DNA and RNA in vivo.

DNA Repair and Cancer

Marc Delarue (PI)

We study the mechanism of DNA Repair of (DNA) Double Strand Breaks  through the so-called Non-Homologous End Joining (NHEJ) process  in mammals using x-ray crystallography and structural studies of pol mu and Tdt

Ligand-gated Ion channels

Marc Delarue (PI)

 We study the structure and function of ligand-gated ion channels by X-ray crystallography to understand i) the gating mechanism (opening of the pore upon agonist binding) ii) the permeation mechanism (transport of ions through the pore) iii) […]
