We use a form of "freeze-trap, kinetic crystallography" to explore the migration of Xe atoms away from the dinuclear heme a(3)/Cu(B) center in Thermus thermophilus cytochrome ba(3) oxidase. This enzyme is a member of the heme-copper oxidase superfamily and is thus crucial for dioxygen-dependent life ...
