Hi everyone,

I want to calculate the binding energy between the protein and the solid surface in Martini coarse-grained MD simulations conducted by Gromacs.

Could you tell me how to do that?

Many thanks, and best wishes.

Hi Tim,

One way to do this could be by using umbrella sampling (US) - see here for our tutorial (on a much simpler system): cgmartini.nl/index.php/tutorials-general...ues#UmbrellaSampling
or metadynamics (again also shown in one of our tutorials: cgmartini.nl/index.php/tutorials-general...on-gmx5/metadynamics ).

Depending on how big is your protein, this may require quite some sampling. Here's a recent example using US - most probably more challenging than your case - have a look: www.nature.com/articles/s41467-020-15554-9
