Dear All,

I would like to work on the R61 DD-peptidase enzyme complexed with penicillin G and cephalosporin C. The antibiotics are covalently bound and up till now I used gromacs/oplsaa for simulations on the apo enzyme but I'm struggling with the FF parametrization of the antibiotics.

Can someone help me?


Read the primary literature for the force field and derive parameters in a compatible way. There is no way around it - parameterization is an extremely difficult task, but without doing it properly, your results will be questionable, at best, and completely wrong, at worst.

Thank you in advance,
