Category Description
Data items in the PDBX_STRUCT_LINK category record details about
covalent linkages in the structure.
Additional Descriptive Information for Depositors
Nonstandard residue linkage. The LINK records specify connectivity between residues that is not implied by the primary structure. Connectivity is expressed in terms of the atom names. This record supplements information given in CONECT records.
