Conformations of ATP on Enzymes The ATP structures shown below are taken from the PDB files indicated. The two starting images use coordinates from the Klotho biochemical compounds database (with hydrogens shown). For side-by-side comparison, all of the models from the crystal structures appear with the ribose sugar in the same orientation. If cations were resolved in the structures, they are labeled with their symbol. Return to ABC97 Home Page
