Histidine-tyrosine protein crosslinks

From Proteopedia

Jump to: navigation, search

Covalent bonds between histidine and tyrosine form in some c-type cytochromes[1][2][3][4][5] and catalases[6][7], making crosslinks between polypeptide chains near the catalytic sites.

Examples

  • 1gge 1999: E. coli catalase HPII.
  • 1v54 2003: Bovine heart cytochrome c oxidase.
  • 2yev 2012: Thermus thermophilus cytochrome caa3 oxidase.
  • 7coh 2021: Bovine heart cytochrome c oxidase.

Other Protein Crosslinks

In addition to the thioester bonds discussed above, other covalent cross-links between polypeptide chains include:
