Antigenicity predictions using the Kolaskar-Tongaonkar algorithm. Threshold (0.993); average (0.993); minimum antigenicity (0.898); maximum antigenicity (1.097). Regions with antigenic propensity scale above 0.993 are antigenic. Window size and center position were 7 and 4, respectively. *Localization of M12 peptide in the CAIII protein (aa 24–35). Matched aa residues are presented in red.
