Catalogue Number ENZ-420
Synonyms Carbonic anhydrase 2, Carbonate dehydratase 2, Carbonic Anhydrase II, CA-II, Carbonic anhydrase C, CAC, CA2, CAII, Car2.
Introduction The enzyme Carbonic anhydrase II having an accession number of NP_414668 is also called carbonate dehydratase which is part of the enzyme family that catalyses rapid inter-conversion of carbon dioxide & water to bicarbonate, carbonic acid and protons (CO2 + H2O ? HCO3? + H+), a reaction that occurs rather slowly in the absence of a catalyst. The majority of carbonic anhydrases enclose a zinc ion in their active site and therefore is classified as metalloenzymes.
The most important function of Carbonic anhydrase is known to preserve acid-base balance in blood and other tissues, and to help transport carbon dioxide of tissues. Carbonic anhydrases have been found in all kingdoms of life. Carbonic anhydrase has 3 different classes: alpha, beta and gamma which share very little sequence or structural similarity, thus far they all perform the same function and require a zinc ion at the active site. Mammalian carbonic anhydrase is monomeric and belongs to the alpha class. Plant carbonic anhydrase is dimeric and belongs to the beta class.
Methane-producing bacteria carbonic anhydrase is trimeric and grows in hot springs which forms the gamma class.
Description Carbonic anhydrase 2 Human Recombinant protein produced in E.Coli containing 260 amino acids (1-260) and having a molecular mass of 29.2 kDa.
The Carbonic anhydrase 2 is purified by proprietary chromatographic techniques.
Source Escherichia Coli.
Physical Appearance Sterile Filtered colorless solution.
Formulation The Carbonic Anhydrase 2 enzyme is supplied in 20mM Tris pH-8, 50mM NaCl, 10% glycerol and 1mM DTT.
Stability Carbonic Anhydrase 2 although stable at 4°C for 1 week, should be stored desiccated below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Biological activity Specific activity is 50-70 nmoles/min/ug and was obtained by measuring the increase in the amount of p-nitrophenol by its esterase activity. Specific activity is defined as the amount of p-nitrophenol that 1ug of enzyme can reduce at 25oC for 1 minute.
Purity Greater than 95.0% as determined by SDS-PAGE.
Usage ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
