Figure 4

Motions of Tyr(B10)29 in going from the photolyzed intermediate (where CO* is in the secondary docking site shown as 2 to the deoxygenated state. The position of CO* in the primary docking site is shown as 1. The figure depicts that approach of the ligand to the metal and rebinding would demand a substantial movement of Tyr(B10)29 from the unliganded configuration. Deoxy, light; photolyzed, dark.
