Functional stability of AMCase against pepsin. Purified AMCase was incubated at 37 °C for 0, 10, 40, and 60 min in stomach-like environment in the presence of pepsin. (a) Samples were analyzed by SDS-PAGE followed by SYPRO Ruby staining. Full-length gel is shown in Supplementary Fig. S5. (b) Determination of the chitinolytic activity. A, AMCase only; P, pepsin only; numbers, incubation time of AMCase and pepsin in minutes. Values in (b) represent mean ± SD conducted in triplicate. Degradation products generated by incubation of (c) crystalline or (d) colloidal chitin with purified enzyme were analyzed by FACE. Full-length gels are shown in Supplementary Fig. S5.
