Note that link records involving MSE ([[selenomethionine]]) generally signify nothing more than MSE being part of a polypeptide chain, but are required because the HETATM MSE residue is covalently linked to the adjacent standard amino acids. | Note that link records involving MSE ([[selenomethionine]]) generally signify nothing more than MSE being part of a polypeptide chain, but are required because the HETATM MSE residue is covalently linked to the adjacent standard amino acids. | ||
Some structures that contain isopeptide bonds lack LINK/_struct_conn records describing these bonds. For example, [[1fma]] has an isopeptide bond between Lys118 chain E, and the carboxy-terminal Gly81 in chain D; [[5jqf]] has an isopepide bond between Asp9 and NH<sub>3</sub> on the amino-terminal Gly1. | Some structures that contain isopeptide bonds lack LINK/_struct_conn records describing these bonds.

Neither has LINK /_struct_conn records for their isopeptide bonds. | ||
