 Given that a [[morph]] is intended to help you compare two structures and does not portray a realistic transition pathway, there are many pathways we can imagine. Below is another one that has structural elements swing away from the core structure in a hinge motion as they change conformation. Another choice in this morph is to have different timings for the distinct changes to be able to follow them one at a time.
-In the morph at full resolution, you can see a large cavity disappearing, the beta sheets acquiring an additional strand from a different subunit (subunits shown in green, blue and red tints), and changes in the core helix bundle along with the formation of the triple helix protrusion.
