Item No.： E0133
Store at： 2～8°C
English name：Carbonic Anhydrase from bovine erythrocytes、
Other name: Carbonic acid dehydratase (bovine red blood cell)
Grade：BR
Vitality：≥2500units/mg protein
Vitality definition：One Wilbur-Anderson (W-A) unit will cause the pH of a 0.02 M Trizma buffer to drop from 8.3 to 6.3 per min at 0°C. (One W-A unit is essentially equivalent to one Roughton-Booth unit.)
Physicochemical properties : Grayish brown or off white powder.The first zinc enzyme discovered in 1940 is also the most important zinc enzyme.More than 80 kinds of zinc enzymes have been reported, ranking first among all kinds of metals.Carbonic anhydrase is one of the main protein components of red blood cells, and its position in red blood cells is second only to hemoglobin.It contains a coiled protein chain and a zinc (Ⅱ) ion.The molecular weight is about 29000.Zinc ion is in the coordination environment of deformed tetrahedron.The most important catalytic reaction is the reversible hydration of carbon dioxide (carboanhydride), which makes it proceed quickly under physiological pH conditions (pH & bcong; 7).As an enzyme that catalyzes the reaction of h2co3co2 + H2O, the factor for the enzyme to accelerate the hydration of carbon dioxide is about 10 ^ 7.
Purpose: Biochemical research.Carbonic anhydrase is a zinc protein (animal origin). It plays a role in the rapid conversion of carbonic acid and bicarbonate ions in red blood cells.
