Crystallization and preliminary X-ray diffraction studies of Tyr167His mutant α-cyclodextrin glucanotransferase from Bacillus macerans.
Improving the specificity of α-cyclodextrin glucanotransferase is a significant issue in the field of α-cyclodextrin production. In this study, a constructed Y167H mutant α-cyclodextrin glucanotransferase with enhanced α-cyclodextrin specificity was successfully expressed and purified. Single crystals were grown using PEG 4000 as a precipitating agent by the hanging-drop vapour-diffusion method...
متن کاملCrystallization and preliminary X-ray diffraction analysis of D53H mutant Escherichia coli cAMP receptor protein.
The Escherichia coli cyclic AMP receptor protein (CRP) is a prokaryotic global transcription activator protein that controls the expression of many different genes. Wild-type CRP can bind to special DNA sequences in the presence of cAMP. The substitution of Asp53 by His results in the CRP* phenotype, which does not require exogenous cAMP. In the present study, the D53H CRP mutant was overexpres...
متن کاملCrystallization and preliminary X-ray studies of mouse centrin1.
Centrins belong to a family of Ca2+-binding EF-hand proteins that play a fundamental role in centrosome duplication and the function of cilia. To shed light on the structure-function relationship of these proteins, mouse centrin1 has been crystallized. The mouse centrin1 has been expressed in Escherichia coli as a GST-centrin fusion protein containing a thrombin protease cleavage site between t...
متن کاملCrystallization and preliminary X-ray diffraction studies of soybean agglutinin.
Soybean agglutinin crystallizes in the monoclinic space group C2 with unit cell dimensions a = 118.6 A, b = 88.9 A, c = 165.9 A, beta = 103.0 degrees and one tetramer of 120,000 Mr per asymmetric unit. The crystals are suitable for high-resolution work.
متن کاملProinsulin: Crystallization and preliminary x-ray diffraction studies.
Bovine proinsulin has been crystallized under a variety of conditions at both neutral and acid pH. Microtechniques were employed with sample weights of about 200 mug and volumes of 5-20 mul. The crystalline preparations all differ from each other morphologically.X-ray photographs of one form, tetragonal bipyramids grown at pH 3 with added ammonium sulphate solution, established the space group ...
