The change in the conformation of residues 393-409 is another result from the reorganization. The final change is the rotation of a 4-helix bundle (located between motif 2 & 3) by 10°. The results of these interactions is the closing up of active site upon lysine binding.

This Sandbox is Reserved from September 14, 2021, through May 31, 2022, for use in the class Introduction to Biochemistry taught by User:John Means at the University of Rio Grande, Rio Grande, OH, USA. This reservation includes 5 reserved sandboxes (Sandbox Reserved 1590 through Sandbox Reserved 1594).
To get started:
  • Click the edit this page tab at the top. Save the page after each step, then edit it again.
  • Click the 3D button (when editing, above the wikitext box) to insert Jmol.
  • show the Scene authoring tools, create a molecular scene, and save it. Copy the green link into the page.
  • Add a description of your scene. Use the buttons above the wikitext box for bold, italics, links, headlines, etc.

More help: Help:Editing. For an example of a student Proteopedia page, please see Photosystem II, Tetanospasmin, or Guanine riboswitch.
