Good day!

I am currently running several MD simulations of a protein-protein complex where one protein, the receptor, is a trimer and the other a theraphotoxin. I would like to ask for inputs on possible thermodynamic analyses on the completed MD simulations. I was thinking of RDF and binding energy, but I do not have that much of a grasp on what possible thermodynamics analyses I can do with this system.

I followed this tutorial for my MD simulation.

Thank you in advance!
