Aurora-A is an essential enzyme which is required for human cells to multiply. Aurora-A has higher activity than normal in many human cancers and is a target for the development of anti-cancer drugs, some of which are in clinical trials. X-ray crystallography is used to characterise how these small molecules interact with Aurora-A, and these data provide information on how they work and allow the production of a new generation of more potent inhibitors.
Electron density at 2.8 Å resolution around the site where one of the inhibitors binds. Knowledge of the geometry and neighbouring atoms will inform drug development.
