Dear Colleagues,

Could you please recommend a force field for protein folding simulations? I found a99sb-disp which is designed for both ordered and disordered proteins, is it a good idea to use this kind of force fields for protein folding simulation?

What else, except the force field, should be considered, maybe some simulation parameters or, the water model? Do you have any recommendations?

Thank you in advance,  
Harut
