Fig. 4From: Characterization of an acetyl xylan esterase from the marine bacterium Ochrovirga pacifica and its synergism with xylanase on beechwood xylana Effect of various metal ions on the relative activity of rAXE. The enzyme reaction was performed with final concentrations of 1 mM and 5 mM for each metal ion. The activity in the absence of a metal ion was taken as the control (100%). b Effect of NaCl on the relative activity and stability of rAXE. The activity at 0 M NaCl in the reaction mixture was taken as the control (100%). Data are presented as mean ± standard deviation (sd), n = 3Back to article page
