There are currently five (alpha, beta, gamma, delta, zeta) classes of carbonic anhydrases (CA's) of which the alpha-class from mammalian sources has been studied to a much greater extent compared to the other four classes. Yet, CA's other than the alpha-class are widely distributed in Nature and play important roles in human health, the global carbon cycle, and industrial applications. In aerobic prokaryotes, beta-class CA's are implicated in maintaining internal pH and CO(2)/bicarbonate… CONTINUE READING
