Biological Activity

Description

Carbonic Anhydrase 3 Protein, Human (His) expresses in E. coli with a His tag at the N-terminus. Carbonic anhydrase 3 (CA III) is a zinc metalloenzyme known to catalyze the reversible hydration of CO2 to HCO3-[1].

Background

Carbonic anhydrase III (CAIII) is a metabolic enzyme and a regulator for intracellular pH. CAIII is an ~30-kDa cytosolic protein present at high levels in liver, adipocytes, and skeletal muscles. It is a low activity enzyme among CA isozymes but is resistant to most sulfonamide inhibitors. CAIII may facilitate rapid conversion of glycolytic intermediates to oxaloacetate and citrate and stimulate their incorporation into fatty acids[2].

Verified Bioactivity

Measured by its esterase activity.The specific activity is >5 pmoles/min/μg.
