CRYSTAL STRUCTURE OF HEW LYSOZYME UNDER PRESSURE OF XENON (8 BAR)
OverviewOverview
X-ray diffraction is used to study the binding of xenon and krypton to a, variety of crystallised proteins: porcine pancreatic elastase; subtilisin, Carlsberg from Bacillus licheniformis; cutinase from Fusarium solani;, collagenase from Hypoderma lineatum; hen egg lysozyme, the lipoamide, dehydrogenase domain from the outer membrane protein P64k from Neisseria, meningitidis; urate-oxidase from Aspergillus flavus, mosquitocidal, delta-endotoxin CytB from Bacillus thuringiensis and the ligand-binding, domain of the human nuclear retinoid-X receptor RXR-alpha. Under gas, pressures ranging from 8 to 20 bar, xenon is able to bind to discrete, sites in hydrophobic cavities, ligand and substrate binding pockets, and, into the pore of channel-like structures. These xenon complexes can be, used to map hydrophobic sites in proteins, or as heavy-atom derivatives in, the isomorphous replacement method of structure determination.
