Histidine-tyrosine protein crosslinks

From Proteopedia

Jump to: navigation, search

Covalent bonds between histidine and tyrosine form in some cytochrome C oxidases[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.

Detection and Visualization

FirstGlance in Jmol automatically detects and alerts you to the presence of any of six types of covalent protein crosslinks (see list below). It provides "one click" tools to zoom in and examine any putative crosslink in detail, including display of the proximal electron density map. See the practical guide FirstGlance/Evaluating Protein Crosslinks. FirstGlance also provides a tool for clear visualization of the much more common disulfide bond crosslinks.

Other Protein Crosslinks

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