Here's some different views of the protein Dipeptidyl Peptidase IV: |
The first image shows the protein as a homodimer without any ligands bound to it. (1PFQ) |
The second image shows four subunits with ligands bound (Beta-D-Manose and N-Acetyl-D-Glucosamine). (1ORV) |
This is a close-up of the N-Acetyl-D-Glucosamine on one of the subunits. (1ORV) |
Here's a space-filling model. (1ORV) |
And a mesh view with space-filling ligands (1ORV). |
And finally, one more view to help visualize the four subunits and surrounding water molecules. (1ORV) |
