CRYSTALLIZATION (Commentary)
ORGANISM
UNIPROT
LITERATURE
crystallized at 8°C using the vapor-diffusion method with a reservoir solution of 2 M (NH4)2SO4 and 2-3% dioxane in 50 mM 2-morpholinoethanesulfonic acid, pH 6.0
-
hanging drop vapor diffusion method, using 1.9-2.2 M ammonium sulfate, 4-6% (w/v) dioxane, 100 mM MES, pH 5.0-5.8
hanging drop vapour diffusion method
-
modeling of structure with naphthalene bound at the active site. The mononuclear iron is coordinated by amino acid residues His208, His213, and Asp362 and a dioxygen molecule is bound in a side-on fashion. The substrate, naphthalene, is found 2.7 to 3.0 A below the dioxygen molecule and is confined in a small substrate binding site which is surrounded by several hydrophobic residues. The amino acid residues with aromatic side chains, including Phe224, Phe202, Phe352, Trp358, and His295 form a small, but rigid, substrate binding site
