Background and Purpose

The function of biomolecules (proteins) is determined by their structures, and the capacity for flexible motion that is intrinsic to those structures. Dynamic events span across different layers of hierarchy in biological organization – from electronic distribution at one end of the spectrum to population dynamics at the other end. They also happen at multiple time scales - from picoseconds for small conformational changes in protein molecules, milliseconds in protein-ligand binding, to seconds to achieve biochemical homeostasis, to days to years for larger phenotypic changes. Ultimately, mechanistic insights of the various dynamic events are crucial for understanding biological function.

Protein mobility can now be experimentally investigated by a number of means which probe a very wide range of timescales and resolutions, including X-ray or neutron crystal structure determination, at atomic resolution, of molecules caught in different conformational states; NMR structure determination, at atomic resolution, of an ensemble of structures existing in solution; FRET techniques which probe the distribution of distances between two or more probe molecules, tethered to a protein; also single-molecule FRET, IR spectroscopy, biochemical probes (cross-linking), mass spectrometry, etc.

A similarly wide range of timescales and resolutions can be probed in silico, with in general a trade-off between the level of detail in a simulation and the timescale or amplitude of motion that can be probed at a given computational expense. The most detailed molecular dynamics methods typically require CPU-weeks or even months to probe motion on a timescale of nanoseconds, making it difficult to relate MD directly to biologically relevant functional motion on timescales of microseconds or slower. Other methods in use include elastic network modelling, rigidity analysis with simulation of flexible motion, coarse-grained MD (e.g. GO, FIRST, FRODA, etc.). Simulations have become the approach of choice to predict structures of biomolecules and their assemblies, dynamics, energetics, molecular recognition, biochemical reactivity. In recent years they have been increasingly explored to study the dynamics of biochemical pathways and larger cellular networks.

This surge of new computational and experimental advancements in the field of structural biology has brought new tools for scientists to inquire into the nature of protein structure and their dynamics. Often each of these techniques performs well under certain conditions and less well under other conditions. This is true both for the experimental as well as computational techniques. Still, at this point in time the techniques start to overlap significantly in their respective ranges of validity and a combined approach across different ranges, from the atomistic, to the molecular and on to coarse-grained and meso-scale models seems not only feasible, but quickly becomes a necessity. Turning this necessity into reality is what our workshop is about.
