 Schematic presentation of the truncated carbonic anhydrase (CA) IV proteins and synthetic peptides. (A) Precursor CA IV is 312 amino acids long. N−-CA IV lacks the N terminal signal sequence (18 amino acid residues), C−-CA IV lacks the C terminal glycosyl phosphatidylinositol (GPI) anchored sequence (28 residues), and N−/C−-CA IV lacks both terminal sequences. (B) Theoretical antigenicity on the amino acid sequence of human CA IV was analysed using the computer. Five sequences representing high antigenicity were selected (indicated by bars with numbers 1–5) and the peptides with these sequences were synthesised.
