Purified recombinant Human Carbonic anhydrase II protein Expression System: E.coli Bioactivity: Specific activity is 50-70 nmoles/min/µg and was obtained by measuring the increase in the amount of p-nitropheno by its esterase activity. Specific activity is defined as the amount of p-nitrophenol that 1ug of enzyme can reduce at 25 °C for 1 minute. Molecular weight on SDS-PAGE will appear higher.

Carbonic anhydrase 2 (CA2) is one of fourteen forms of human alpha carbonic anhydrases. Carbonic anhydrase catalyzes reversible hydration of carbon dioxide. CA2 is a cytosolic enzyme with the highest activity among all known CAs. Mutations in the CA2 gene result in the CA2 deficiency syndrome, an autosomal recessive disorder that produces osteopetrosis, renal tubular acidosis and cerebral calcification. Recombinant human CA2 was expressed in E. coli and purified by using conventional chromatography.
