1. The structure of Mb showing the different internal cavities: four xenon-binding sites (Xe1–Xe4), two Phantom sites (Ph1 and Ph2) and the distal pocket (DP) above the heme plane and near the distal histidine (E64).
The structure of Mb showing the different internal cavities: four xenon-binding sites (Xe1–Xe4), two Phantom sites (Ph1 and Ph2) and the distal pocket (DP) above the heme plane and near the distal histidine (E64). A mesh outlines the molecular surface, which encloses the internal cavities. The blue dotted circle denotes the ligand binding position, and the red dotted circle traces the primary docking site.
