Effects of NaCl and CaCl 2 on thermostability of recombinant AprX-SK37. The enzyme was pre-incubated at either 40 (a) or 55°C (b) in 100 mM Tris-Glycine pH 9.5 containing; 5 mM CaCl2 (black triangle): 5 mM CaCl2 and 1 M NaCl (black square): 15 mM CaCl2 (black diamond): 15 mM CaCl2 and 1 M NaCl (cross). Residual enzyme activities were measured at 55°C under standard assay conditions.
