Dear All,

I have a very simple question :

Is it possible to minimize (for instance) a peptide with a NH2_terminal
groupe and a COOH_terminal groupe with the amber94...98 force fields
instead of the NH3+_terminal and COO-_terminal groupes with amber_5 or 6

If I look in the amino acid database (,,, I see ONLY 2 types of amino acids (AA):
NH3+_AA (N-term) and NH_AA (peptide bond) but I do not see the NH2_AA
(N-term) one.
COO-_AA (C-term) and CO_AA (peptide bond) but I do not see the COOH_AA
(C-term) one.
