Crystallization and preliminary X-ray crystallographic study of disproportionating enzyme from potato.

چکیده
Disproportionating enzyme (D-enzyme; EC 2.4.1.25) is a 59 kDa protein that belongs to the alpha-amylase family. D-enzyme catalyses intramolecular and intermolecular transglycosylation reactions of alpha-1,4 glucan. A crystal of the D-enzyme from potato was obtained by the hanging-drop vapour-diffusion method. Preliminary X-ray data showed that the crystal diffracts to 2.0 A resolution and belongs to space group C222(1), with unit-cell parameters a = 69.7, b = 120.3, c = 174.2 A.

In this paper, the purification, crystallization and preliminary X-ray crystallographic studies of human carnitine acetyltransferase are reported. Recombinant human carnitine acetyltransferase crystals were grown by the hanging-drop vapor-diffusion method and belong to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 137.65, b = 84.76, c = 57.65 A and one molecule per a...
متن کاملCrystallization and preliminary X-ray crystallographic studies on a Kunitz-type potato serine protease inhibitor.
Interest in protease inhibitors has been renewed because of their potent activity in preventing carcinogenesis in a wide variety of in vivo and in vitro model systems. Potato tubers contain a wide range of such protease inhibitors. In cv. Elkana potato tubers, protease inhibitors represent about 50% of the total amount of soluble protein. Potato serine protease inhibitor (PSPI), one of the isof...
متن کاملCrystallization and preliminary x-ray crystallographic data of dienelactone hydrolase from Pseudomonas sp. B13.
Dienelactone hydrolase (EC 3.1.1.45) from Pseudomonas sp. B13 has been crystallized in a form suitable for high resolution x-ray diffraction study. The crystals are orthorhombic, the space group being P212121, with unit cell dimensions a = 48.9 A, b = 71.2 A, and c = 77.5 A. There appears to be 1 molecule in the asymmetric unit.
متن کاملCrystallization and preliminary crystallographic analysis of endonuclease VIII in its uncomplexed form.
The Escherichia coli DNA repair enzyme endonuclease VIII (EndoVIII or Nei) excises oxidized pyrimidines from damaged DNA substrates. It overlaps in substrate specificity with endonuclease III and may serve as a back-up for this enzyme in E. coli. The three-dimensional structure of Nei covalently complexed with DNA has been recently determined, revealing the critical amino-acid residues required...
