Crystallization and preliminary X-ray diffraction studies of mammalian purple acid phosphatase.
The oxidized form of purple acid phosphatase from pig allantoic fluid has been crystallized in the presence of phosphate using the hanging-drop technique. The crystals belong to the space group P2(1)2(1)2(1) and have unit-cell parameters a = 66.8, b = 70.3, c = 78.7 A. Diffraction data collected from a cryocooled crystal using a conventional X-ray source extend to 1.55 A resolution. A knowledge...
متن کاملCrystallization and preliminary X-ray diffraction
The amyloidogenic Leu55Pro variant of transthyretin has been expressed, purified and crystallized in space group C2. The cell constants are a--149.99, b = 78.74, c = 98.95A, = 100.5 ° and the crystals diffract to 2.7,~ resolution. There are eight monomers in the asymmetric unit giving a V M = 2.6,~,3 Da -w and 53% solvent content. In the wild-type protein, the crystals are orthorhombic with two...
متن کاملA purple acid phosphatase from sweet potato contains an antiferromagnetically coupled binuclear Fe-Mn center.
A purple acid phosphatase from sweet potato is the first reported example of a protein containing an enzymatically active binuclear Fe-Mn center. Multifield saturation magnetization data over a temperature range of 2 to 200 K indicates that this center is strongly antiferromagnetically coupled. Metal ion analysis shows an excess of iron over manganese. Low temperature EPR spectra reveal only re...
متن کاملAmino Acid Composition, Crystallization and Preliminary X-ray Diffraction Studies of Guanylonbonuclease from Streptomyces Aureofaciens
The amino acid composition and preparation of crystals for X ray diffraction analysis of guanylonbonuclease isolated from Streptomyces aureofa ciens is described. Single crystals have been grown from ammonium sulphate solutions. The crystals are orthorombic, space group P 2i2]2, cell dimmensions a = 6.47 nm, b = 7.89 nm, c = 3.93 nm. There are two molecules of a molecular weight of 10 600 in t...
متن کاملPurification, crystallization and preliminary X-ray diffraction studies of recombinant class A non-specific acid phosphatase of Salmonella typhimurium.
The phoN gene of Salmonella enterica sv. Typhimurium strain MD6001 was cloned in the multicopy plasmid pBluescript SK(-). The nucleotide sequence of the cloned gene differs from the corresponding S. typhimurium LT2 sequence at 23 residues, leading to 15 amino-acid differences, but was very close to the S. typhi phoN sequence (only three nucleotide and two amino-acid differences). The recombinan...
