Figure 3. Stabilities of the cotAs from B. clausii and B. subtilis vs. temperature and pH 8 (circles, solid line), 9 (squares, broken line) and 10 (triangles, dotted line).
(A) B. subtilis cotA at 50°C; (B) B. subtilis cotA at 70°C; (C) B. subtilis cotA at 80°C; (D) B. clausii cotA at 50°C; (E) B. clausii cotA at 70°C; (F) B. clausii cotA at 80°C. Activities were normalized to the starting activity before heat incubation.
