MD Simulations of (Membrane) Proteins

The continuous research efforts in Molecular Biophysics have provided an amazing number of solved protein structures. Whether obtained by NMR or X-rays diffraction from protein crystals, these structures are just snapshots of the proteins, often taken in an experimental condition that is far from the real cellular environment in which these proteins perform their function.

These limitations can be partly overcome by applying Molecular Dynamics simulation to the analysis of available protein structures. The field of research is rather mature, with over 40 years of developments and achievements, marked also by the massive employment of open-source software packages, readily available on almost all supercomputer centers in Europe and even on local clusters or desktop computers.

Although theoretical methods are robust, their validation strictly requires a careful comparison with experimental data: in addition, it is actually through this endless interplay between theory and experiments that major advances in molecular biophysics can be achieved. Therefore, all the systems investigated within this research line do feature an experimental counterpart, whether located in Trento or not.

We have developed a particular preference and experience for membrane proteins, but there are no limits: as far as there are reliable data to compare with, we are open to any collaboration with experimental groups around the world and (why not?) even beyond: the fantastic implications of extra-terrestrial life would open an entirely new dream playground for molecular biophysics…
