Protein-ligand was created by imankatouzian
Good day,

I want to simulate the interaction of a protein with a molecule (ligand)
I am using the martini force field with the simulation time of more than 5 micro seconds
Is there a tutorial which can help me in this regard

Thanks

At the moment, such a tutorial is not there. We plan to make one in the near future (next few months). For the moment, you can start by creating a protein model ( www.cgmartini.nl/index.php/tutorials-gen...n-gmx5/proteins-gmx5 ) and a model for the ligand(s) ( www.cgmartini.nl/index.php/tutorials-gen...ng-new-molecule-gmx5 ), if you haven't done so yet.

I will also try to remember to post something on this thread once a protein-ligand binding tutorial will be available.

Dear riccardo,

Many thanks for your response.
I have a small molecule which I want to simulate it using CG, should I apply the above-mentioned tutorial you sent me or is there another means to do it since the lipid in the tutorial was a biopolymer and a big molecule.

Thanks

I don't understand this last part of your post "since the lipid in the tutorial was a biopolymer and a big molecule"?

The tutorial I linked above for the parametrization of small molecules is what you need if your ligand is an arbitrary small molecule. If you suspect that your ligand is very similar to a topology which may be listed among the topologies available in the Downloads section ( cgmartini.nl/index.php/force-field-parameters ), please check that out carefully. If you find even only fragments of your molecule for which a Martini model already exist, you can start to build from there.

*EDIT: There was a typo, now corrected ("If you find...")

We published a tutorial regarding protein-ligand binding simulations (with Martini 3). Please see here: cgmartini.nl/index.php/martini-3-tutoria...all-molecule-binding
