Dear Dr. Spoel
Good day.

I am a beginner in Gromacs and having some problem in running energy
minimization. I am working with an enzyme that has a Zn bound to four
residues (3 cys and 1 his). I am trying to run a md simulation. But
after the minimization I always found the Zinc coming out of the enzyme.
I ran the minimization both with generating counter ions and without
generating. The result is same. Do I need to take any special care to
work with metalloenzyme ?

 > Yes. You need restraints.

Any suggestion from you will be highly useful for me.
Best regards
Abhik Mukhopadhyay
