Carbonic Anhydrase VB / CA5B Protein (His tag) (recombinant human)

Activity: Measured by its esterase activity. The specific activity is >150 pmoles/min/µg. Protein Construction: A DNA sequence encoding the mature form of human CA5B (Q9Y2D0) (Cys 34-Pro 317) was fused with a polyhistidine tag at the C-terminus and an initial Met at the N-terminus. Sequence: Cys 34-Pro 317. Fusion tag: C-His Endotoxin: Please contact us for more information. Apparent Molecular Mass: 34 kDa. Protein function: Carbonic anhydrase 5B, also known as carbonate dehydratase VB, carbonic anhydrase VB, CA-VB and CA5B, is a member of the alpha-carbonic anhydrase family. The strongest expression of CA5B / CA-VB is in heart, pancreas, kidney, placenta, lung, and skeletal muscle. It is not expressed in liver. Carbonic anhydrases (CAs) are a large family of zinc metalloenzymes first discovered in 1933 that catalyze the reversible hydration of carbon dioxide. CAs participate in a variety of biological processes, including respiration, calcification, acid-base balance, bone resorption, and the formation of aqueous humor, cerebrospinal fluid, saliva, and gastric acid. CAs show extensive diversity in tissue distribution and in their subcellular localization. CA5B / CA-VB is localized in the mitochondria and shows the highest sequence similarity to the other mitochondrial CA5A / CA-VA. CA5B / CA-VB has a wider tissue distribution than CA5A / CA-VA, which is restricted to the liver. The differences in tissue distr Protein function: Reversible hydration of carbon dioxide.
