Sequence of the high-activity equine erythrocyte carbonic anhydrase: N-terminal polymorphism (acetyl-Ser/acetyl-Thr) and homologies to similar mammalian isozymes.
The amino acid sequence of the high-activity equine erythrocyte carbonic anhydrase (CA-II) has been determined. Two different N-termini are noted, the C1 form having an N-acetyl-serine and the C2 form an N-acetyl-threonine. The sequence of the equine enzyme is most homologous to the human CA-II isozyme, with 224 of the 259 residues being identical.
