Hi I am refining a protein-rna complex structure. The rna has a phosphate group at 5-terminus. I noticed there is a 5p*END in the dictionary list of refmac, so when I loaded a cif file containing lines bleow,
# data_comp_list loop_ _entity_mod_id _entity_mod_entity_id _entity_mod_mon_id _entity_mod_set_num 5p*END Cchain Ar 1 # but the program still failed during running. Could anyone give me some suggestions ? Thanks a lot! Leon
