Hi AAA ATPase modelers Could anyone send me the .cif file to define the link between ADP and a BeFx ion? I’m hoping this has not only the revised angle/bond info between O3B and Be but also the new angle between the Be and Fs different from the planar simple ion. AND, for my hexamer I assume the apply_link.def file then just reads with repetitive 5-line groups: refinement.pdb_interpretation.apply_cif_link { data_link = ADP-BEF residue_selection_1 = chain A and resname ADP and resseq 901 residue_selection_2 = chain A and resname BEF and resseq 902 } Where I change out the chain name but keep calling them residues_selection1 and 2?
