1.11.1.21 3-Amino-1,2,4-triazole 156% relative catalase activity at 10 mM, 121% relative peroxidase activity at 10 mM 1.11.1.21 ammonium sulfate additions of ammonium sulfate even at weak concentrations (10 to 70 mM) stimulate catalatic activity measured in the presence of 1.5 M NaC1 by about 30% 1.11.1.21 NaCl 76% stimulation of catalase by addition of 10 mM NaCl 1.11.1.21 NaCl peroxidase activity is maximal at NaCl concentrations above 1 M, although catalase activity requires 2 M NaCl for optimal function 1.11.1.21 NaCl with NaC1, maximum activity is observed near 0.5-0.7 M
