From: Elastic network model of allosteric regulation in protein kinase PDK1
The crystal structure of the protein kinase PDK1. The protein is shown as a solid ribbon and the agonist PS48 as a stick diagram, protein data bank accession 3HRF. The activation loop is highlighted in black. To the right is the same protein fold as a Cα ENM, with the agonist replaced by three nodes. The node positions relative to PS48 are shown above.
