Crystallization and preliminary X-ray analysis of human carbonic anhydrase III.
Carbonic anhydrases catalyze the interconversion of carbon dioxide to bicarbonate. Human carbonic anhydrase isozyme III with a C-terminal hexahistidine tag was overexpressed in Eschericha coli, purified and crystallized. Diffraction data (93.4% completeness) were collected to 2.2 A resolution on an in-house R-AXIS IV++ image-plate system with Osmic mirrors and a Rigaku HU-H3R CU rotating-anode ...
متن کاملbeta-carbonic anhydrase from Pisum sativum: crystallization and preliminary X-ray analysis.
Recombinant beta-carbonic anhydrase from the garden pea, Pisum sativum, was purified to homogeneity and crystallized. Crystals belong to the orthorhombic space group C222, with unit-cell parameters a = 136.3, b = 142.5, c = 201.4 A, alpha = beta = gamma = 90 degrees. Crystals typically diffracted anisotropically, with a maximal resolution of 2.0 A in the strongest direction. The calculated Matt...
متن کاملIdentification, cDNA cloning, expression, crystallization and preliminary X-ray analysis of an exceptionally halotolerant carbonic anhydrase from Dunaliella salina.
An extracellular alpha-type carbonic anhydrase (dCAII) from the salt-tolerant alga Dunaliella salina differs from its mesophilic counterparts in remaining active from zero to multimolar salt concentrations. To gain insight into the outstanding salt tolerance of dCAII, the enzyme was functionally overexpressed in Escherichia coli, purified by affinity chromatography and crystallized by the hangi...
متن کاملPurification, crystallization, and preliminary X-ray data for porcine fumarase.
Single crystals of fumarase purified from pig heart have been prepared from solutions containing polyethylene glycol. The crystals give diffraction data corresponding to Bragg spacings of 2.0 A and contain a single subunit of the enzyme in the asymmetric unit of the C222 unit cell. Therefore, the subunits of this tetrameric molecule are arranged with the point symmetry group 222. The present pu...
متن کاملStructural study of X-ray induced activation of carbonic anhydrase.
Carbonic anhydrase, a zinc metalloenzyme, catalyzes the reversible hydration of carbon dioxide to bicarbonate. It is involved in processes connected with acid-base homeostasis, respiration, and photosynthesis. More than 100 distinct human carbonic anhydrase II (HCAII) 3D structures have been generated in last 3 decades [Liljas A, et al. (1972) Nat New Biol 235:131-137], but a structure of an HC...
