Stability
Stable at room temperature and pressure
Molecular structure
A protein containing zinc. It can catalyze the decomposition of carbon oxygen bonds and is a powerful catalyst for the reversible hydration of carbon dioxide, acetaldehyde, and related carbonyl compounds. There are two Isozyme A and B. Soluble in water and dilute buffer solution. Enzyme reaction: H++HCO3=CO2+H2O. Isoelectric point PI5.9 (B). Absorbance (A1% 280) 19.0 (B). Inhibitors include univalent anions such as cyanogen (CN -), cyanate (NCO -), hydrogen sulfide (HS -), thiocyanate (NCS -), Azide (N3-), acetazole (sulfonyl) amine and aromatic sulfonamides, low concentration metal ions, mercaptan, rosin salt {K [Fe4S3 (NO7)]}.
Unit definition: at 0 ℃, the speed of reducing the pH of 0.01mol/L Barbital buffer solution containing saturated CO2 from 8.2 to 6.3 is twice as fast as the blank enzyme amount, which is 1 unit.
