Hi amber users,
I have a modified residue for which I need to provide force field
parameters. it is a 2-aminofluorene connected to C8 of a guanine. the
linkage site looks like:
N7 H C==C
\ | // \\
Gua C8-N-C C--
/ \\ //
N9 C==C AF
\
The double bonds refers to aromatic ring. Only part of the guanine and
part of the aminofluorene are given above.
I would like to know what atom type is the most appropriate for the
Nitrogen atom that links guanine C8 and the AF ring...(that is, the
middle N atom in above structure).
Possible candidates are N2 or N* in parm99.dat (after all what is the
difference between N2 and N* in this file?)
any comments or suggestions are welcome. thanks.
Lihua
