Dear Qixu,
You can take a look at existing entries which have link records between
1_555 and another symmetry molecule. For example 5BQC which has various
of these.
mmCIF:
#
loop_
_struct_conn.id
_struct_conn.conn_type_id
_struct_conn.pdbx_leaving_atom_flag
_struct_conn.pdbx_PDB_id
Dear all,
I'm working on the refinement of a crystal structure. In the structure, one
crystal packing interface is mediated by a compound with two coordinate
covalent bonds to two macromolecules from different asymmetric units. Thus
I need to specify two "LINK" records in the head of pdb file.
