Esterase and hydrase activity of carbonic anhydrase-I from primate erythrocytes

Carboxylic esterase activity toward the acetate and butyrate esters of [alpha]- and [beta]-naphthol is associated with two forms of erythrocyte carbonic anhydrase (CA-I, CA-II) in man (Tashian , 1963) and other primate species. Of 22 primate species tested, erythrocyte CA-I from the rhesus macaque () and doguera baboon () were among those forms showing high specific esterase activity; in comparison, human and chimpanzee () CA-I exhibit moderate esterase activity. This report compares the hydrolase and hydrase activities of partially-purified CA-I from human, chimpanzee, baboon, and rhesus hemolysates.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/32150/1/0000204.pd
