Biochemical properties of Lp_0179 and Lp_2757 α-amylases from L. plantarum WCFS1. a Relative activity of Lp_0179 (filled square) and Lp_2757 (filled triangle) versus pH. b Relative activity of Lp_0179 (filled square) and Lp_2757 (filled triangle) versus temperature. Thermal stability of Lp_0179 (c) and Lp_2757 (b) after preincubation at 22 °C (filled diamond), 30 °C (filled square), 37 °C (filled triangle), 45 °C (cross), and 65 °C (filled circle) in MOPS buffer (50 mM, pH 7) containing 20 mM NaCl and 1 mM DTT; at indicated times, aliquots were withdrawn, and analyzed as described in the Methods section. The experiments were done in triplicate. The mean value and the standard error are shown. The observed maximum activity was defined as 100%
