1.13.11.49 | enzyme is a homopentamer, with presence of one b-type heme per monomer |
1.13.11.49 | in complex with thiocyanate and azide, to 0.976 and 1.0 A resolution, respectively. The crystal structure of the Cld-azide complex reveals a single well-defined orientation of the azide molecule in the heme pocket. EPR shows a pH-dependent heme structure, probably due to acid-base transitions of the surrounding amino-acid residues stabilizing azide |
1.13.11.49 | molecular dynamics simulations for binding of cyanide, chlorite, and hypochlorite with the enzyme in the ferrous, ferric, and compound I state. During reaction, a large portion of hypochlorite escapes from the heme cavity and enters the bulk phase. Leakage of hypochlorite in the mutant R173A is higher than that in the wild-type protein |
1.13.11.49 | mutant enzymes Q74V and Q74E, sitting drop vapor diffusion method, using 0.1 M MES (pH 6.5), 0.15 M MgSO4, 28% (w/v) polyethylene glycol 3350, and 3% (v/v) glycerol |
1.13.11.49 | purified recombinant His-tagged enzyme, sitting-drop vapor diffusion technique and a nanodropdispensing robot, from 1.0 M Na2HPO4-NaH2PO4, pH 8.2, at 22°C, 1 week, X-ray diffraction structure determination and analysis at 2.10 A resolution |
1.13.11.49 | purified recombinant His-tagged wild-type and mutant enzymes with bound cyanide, 22°C, sitting drop vapour diffusion method, X-ray diffraction structure determination and analysis at 1.85-2.70 A resolution |
1.13.11.49 | recombinant protein, buffer-exchanged into 20 mM HEPES, pH 7.0, hanging-drop vapor diffusion, 16% PEG 8000, 0.2 M calcium acetate, 90 mM MES, pH 6.5, 293 K, chrystals appear after 2 h, co-crystals with substrate analogues sodium nitrite and sodium cyanide under same conditions |
1.13.11.49 | sitting drop method |
1.13.11.49 | thiocyanate inhibited enzyme with incorporated heme, crystals grown from well solution containing 100 mM Mes buffer (pH 5.5), 25% polyethylene glycol monomethyl ether 2000, 0.3 M KSCN, 5% glycerol, 160-260 mM (NH4)2SO4, before data collection crystals are soaked in a solution of the mother liquor including 16% glycerol, crystal is flash-frozen and kept at -173°C (100 K) for multiple anomalous dispersion (MAD) with synchrotron radiation |
