Hi ,folks.

  In 2003 amber force field (Duan et al) , during the fitting procedure, "charge of each amino acid was represented by a dipeptide fragment consisting of the amino acid residue and the terminal groups (Ace- and -Nme)". And charge of each atom in molecue (Ace- and -Nme) was fitted using RESP method .

What technique was used to guarantee total charge for each amino acid residue was 0 ,-1 or +1.


Many thanks .!!!
