A Different Structural Feature for Carbonic Anhydrases in Human Erythrocytes. Sixteen CA isozymes have been described so far in mammals. In plants, the role of carbonic anhydrase may be to catalyse the inter‐conversion of bicarbonate and carbon dioxide, to provide ‘carbon dioxide’ in the form appropriate for carbon‐fixing reactions. The zinc metal is always bound to histidines 93, 95, and 118 (mature chain numbering). Mammalian carbonic anhydrases also catalyse the hydrolysis of some esters and the hydration of aldehydes.

The mammalian isoenzymes differ from one another in their amino‐acid compositions (the difference in serine contents being a consistent finding in a number of species), in their physical properties (isoelectric pH, retention by ion‐exchange resins, electrophoretic mobility) and in their kinetic properties. Histochemical localization of carbonic anhydrase in vertebrate nervous tissue. 1973, and Lin and Deutsch 1974). Part A. Carbonic Anhydrase C in the Human Renal Medulla. While the red cells of most mammalian species so far studied contain both ‘high activity’ and ‘low activity’ isoenzymes, the latter is reported to be absent from the erythrocytes of sheep, ox and dog.
