Despite its name, the carbonic anhydrase VIII (CA8) protein lacks carbonic anhydrase catalytic activity. This distinguishes CA8 from its typical functions related to carbonic anhydrase, an enzyme known for its ability to catalyze the reversible hydration of carbon dioxide. Carbonic Anhydrase 8 Protein, Mouse (His) is the recombinant mouse-derived Carbonic Anhydrase VIII/CA8 protein, expressed by E. coli , with C-His labeled tag.
