Isopeptide bonds in the following examples are specified in LINK/_struct_conn records. | |||
*The capsid of the HK97 bacteriophage contains isopeptide bonds that cross-link the protein [[chains]] into a protein ''chain mail'' <ref>PMID: 22297521</ref><ref>PMID: 10572124</ref><ref name="wikoff2000">PMID: 19091865</ref>. However, these do not occur in the [[asymmetric unit]] of [[1ohg]]<ref>PMID: 11000116</ref>. They can be visualized in the [[biological unit]], which is the full virus capsid, but that is technically challenging. | *The capsid of the HK97 bacteriophage contains isopeptide bonds that cross-link the protein [[chains]] into a protein ''chain mail'' <ref>PMID: 22297521</ref><ref>PMID: 10572124</ref><ref name="wikoff2000">PMID: 19091865</ref>.
