trout pepsins exhibit the highest enzyme activity at pH 3.0 (isoform P-I) and 2.5 (isoforms P-II and P-III); P-I shows a broad optimum in the pH range from 1.5 to 4.0, while the optima for P-II and III are restricted to the pH range from 2.0 to 3.0.at pH 4.0. Isoform P-I retains 94% activity, while isoforms P-II 72 and P-III have 65% activity. All three isoforms show residual activity of about 20% at pH 6.0 |
