Subject: [AMBER] Metalloproteins - Ligand Protonation

Dear AMBER

I hope to find anybody worked before on Metalloprotiens.

I am working on simulation of MMP-3 inhibited with Hydroxamate ligand (CH3-C(O)-N(H)-OH).

I would like to enquire about the protonation state of Hydroxamate
inside the protein, when I build the ligand, which state should I use
for the ligand, protonated or not?

I am really confused, and no paper mentioned this issue.

Thanks in advance

Bill
