Dear Johny,
Perhaps you don't need to define your SMD routes precisely along a cuved
path, but it may
turn out that a few (say, 3 or 4) turning points on a given pathway are
sufficient to smoothly
drive your ligand out of the enzyme.
You have to make educated guesses to define the turning points.
Please take a look at Leandro Martínez's work:
J. Phys. Chem. B 2008, 112, 10741–10751
This multi-point SMD approach preserves the desired physics of the force
profile.
Best,
munir
