Crystallization and preliminary crystal data of iron-containing superoxide dismutase from Pseudomonas ovalis.

چکیده
Large single crystals of iron-containing superoxide dismutase from Pseudomonas ovalis were prepared from 50% saturated ammonium sulfate solution, at pH 4.5, on gentle evaporation of the solvent at 4 degrees. The crystals were monoclinic, space group P2, with unit cell dimensions a = 81.9 A, b = 49.0 A, c = 61.0 A, and beta = 106 degrees. Considerations of cell volume and protein molecular weight indicated 1 molecule of superoxide dismutase in the assymmetric unit, the smallest number reported so far for superoxide dismutases.

Crystallization and preliminary X-ray diffraction studies of the iron superoxide dismutase from the eukaryote Vigna unguiculata
Superoxide dismutases are a family of metalloenzymes that catalyze the dismutation of superoxide radicals into molecular oxygen and hydrogen peroxide, and thus represent a primary line of defence against oxidative stress. The iron-containing superoxide dismutases are only found in prokaryotes and plants. The iron superoxide dismutase of Vigna unguiculata (cowpea) consists of two polypeptides of...
متن کاملImproved three-dimensional growth of manganese superoxide dismutase crystals on the International Space Station.
Manganese superoxide dismutase was crystallized in microgravity with 35 PCAM experiments (Protein Crystallization Apparatus for Microgravity) on the ISS (International Space Station) from 5 December 2001 to 19 April 2002. Crystals were very large in size and could easily be seen by eye. Crystals with 0.45 x 0.45 mm cross-sections and of up to 3 mm in length were obtained in several drops: an 80...
متن کاملSaturation behavior of superoxide dismutation catalyzed by the iron containing superoxide dismutase of E. coli B.
The iron containing superoxide dismutase from E. coli B is shown to catalyze superoxide dismutation by a mechanism which exhibits saturation kinetics. This behavior is quite different from that observed previously with bovine Zn/Cuand iron-containing superoxide dismutase from P. leiosnathi. Two parameters of catalysis were measured in the pH range 7.2 to 10.4: k was found to be independent of p...
متن کاملCrystallization and preliminary X-ray analysis of the outer membrane pyoverdine receptor FpvA from Pseudomonas aeruginosa.
FpvA, the pyoverdine outer-membrane receptor from Pseudomonas aeruginosa, is involved in iron uptake when bacteria grow under iron limitation. Crystals of the in vivo pyoverdine-loaded FpvA were obtained under several crystallization conditions using different detergents. A native data set was collected at 3.6 A resolution and a three-wavelength MAD data set was collected at 3.6 A resolution us...
متن کاملA pulse-radiolysis study of the catalytic mechanism of the iron-containing superoxide dismutase from Photobacterium leiognathi.
The mechanism of the enzymic reaction of an iron-containing superoxide dismutase purified from the marine bacterium Photobacterium leiognathi was studied by using pulse radiolysis. Measurements of activity were done with two different preparations of enzyme containing either 1.6 or 1.15 g-atom of iron/mol. In both cases, identical values of the second-order rate constant for reaction between su...
