Dear Amber users, There are two phosphorylated residues in my protein, TPO183 (phosphorylated threonine) and PTR185 (phosphorylated tyrosine).I have modified the two residues in the pdb file as follows: the residue name of the atoms belong to the THR183 and TYR185 were modified back to THR and TYR respectively; the residue name of the two phosphate groups were deleted and the residue number of them were modified to 359 and 360 (the last residue number in my protein was 358, so I add two residue number for them).Though the parameters of the phosphate group atoms were included in the amber9/dat/leap/parm/parm99.dat, the 8 phosphate group atoms were not recognized by leap. so, What I want to know is that how can I deal with the two phosphorylated residues. Thanks very much!Yaxue Zhao Source pdb fileHETATM 1434 N TPO 183 HETATM 1435 CA TPO 183
