| Abstract: | Nonaqueous fractionation of leaves of the cotton plant suggested that carbonic anhydrase was associated with the chloroplasts. Activity of this enzyme in aqueous extracts prepared in media containing no reductants was stable at 4°. Response to sulfhydryl reagents varied. The results indicated that thiol groups, necessary for the activity of the enzyme, were partially protected from oxidation. |
