Some biochemical properties of TanA Sg protein. (A) Relative activity versus pH. (B) Relative activity of TanASg versus temperature. (C) Thermal stability of TanASg after preincubation at 22°C (filled diamond), 30°C (filled square), 37°C (filled triangle), 45°C (cross), 55°C (star), and 65°C (filled circle) in phosphate buffer (50 mM, pH 6.5); at indicated times, aliquots were withdrawn, and analyzed as described in the Methods section. The observed maximum activity was defined as 100%. (D) Relative activity of TanASg after incubation with 1 mM concentrations of different additives. The activity of the enzyme in the absence of additives was defined as 100%. The experiments were done in triplicate. The mean value and the standard error are shown. Asteriks indicate a p value <0.05.
