Abstract
The complete amino acid sequence of carbonic anhydrase I (CA I) isolated from the red cells of the rhesus macaque ( Macaca mulatta ) is presented. This sequence was obtained by aligning peptides derived from various fragmentation procedures with the fully characterized sequence of human CA I. When the peptides of rhesus CA I were ordered in this manner, 13 of the 260 residues were found to differ from the human CA I sequence. The known markedly higher specific esterase activity of rhesus CA I compared to human CA I could not be correlated with any changes in residues postulated to be within 10 Å of the single zinc ion at the active site.
