“…Also, there are three known acatalytic forms called the CA‐related proteins VIII, X and XI (CARP VIII, X, and XI) As an outcome, multitude of these isoenzymes is drug aims for anticonvulsants, diuretics, antitumor drugs/tumor imaging factors, antiarthritis, antineuropathic pain factors, and antiglaucoma factors. The CA is an extremely efficacious catalyst of reversible interconversion of CO 2 and . The rate fixed of uncatalyzed reaction is 0.037 s −1 while CA enhances the rate by nearly 10 6 times …”
