Example LINK and LINKR records, corresponding to the covalent linkage of the NZ atom in lysine (LYS) and the C4A atom in pyridoxal phosphate (PLP). In this case, LYS-A226 is linked to PLP-A501. The two fields marked `1555' correspond to symmetry operators (in this case the linked atoms are located within the same asymmetric unit). LINK and LINKR records differ only in the final field: LINK records have a link distance (for example `1.27'), whereas LINKR records have a link identifier (for example `LYS-PLP'). For further details about the format of LINK records, see Callaway et al. (1996BB13).
