The salt tolerance and thermostability of AnEGL and its mutants. A Influence of NaCl concentration on activity at 50 °C pH 4.0. B The thermostability at 65 °C pH 4.0 with the presence of 4.5 M NaCl. The mutation sites of mutant 1–8: mutant 1 (D95N), mutant 2 (D99N), mutant 3 (E55Q), mutant 4 (D114N), mutant 5 (E157Q), mutant 6 (K159T), mutant 7 (D95N, D99N), mutant 8 (E55Q, D114N, E157Q, K159T)
