COMMENTARY 
LITERATURE
0 - 50
purified recombinant enzyme, stable up to, over 90% activity remaining
25 - 80
-
95% activity at 25°C, 80% activity at 40°C, less than 20% activity at 50°C, less than 10% activity at 60 and 70°C, inactive at 80°C
25 - 85
-
between 60 and 70°C 50% of the enzyme activity is lost, at 85°C 50% of the protein molecules are denatured, the residual activity is 4%

60
70
80
purified recombinant wild-type enzyme, sharp decline during incubation at 80°C, half-life is 1.5 h

-
5 min, resistant to incubation with 0.08% SDS, 1 M guanidine hydrochloride, 4 M urea, 45% ethanol or 50% dimethyl sulfoxide
30
-
5 min, about 50% loss of activity after incubation with 0.08% SDS, 1 M guanidine hydrochloride, 4 M urea, 45% ethanol or 50% dimethyl sulfoxide
40
-
the decrease in the enzyme activity at incubation temperatures over 40°C is consistent with the decrease in the amount of bound pyridoxal 5'-phosphate, no effect on stability at lower temperatures, 0-30°C
40
1 h, quick loss of activity in absence of pyridoxal 5'-phosphate
50
purified recombinant wild-type enzyme, 12 h, completely stable, the first several hours of incubation at 50-70°C help in thermoactivation of the enzyme
50
pH 8.3, 1 h, stabilized up to 50°C in presence of excess amounts of pyridoxal 5'-phosphate, 0.4 mM, complete inactivation in absence of pyridoxal 5'-phosphate
50
the enzyme is stabilized up to 50°C in presence of 0.4 mM pyridoxal 5'-phosphate
50
the enzyme is stabilized up to 50°C in presence of 0.4 mM pyridoxal 5'-phosphate
50
the enzyme is stabilized up to 50°C in presence of 0.4 mM pyridoxal 5'-phosphate
50
the enzyme is stabilized up to 50°C in presence of 0.4 mM pyridoxal 5'-phosphate
60
purified recombinant wild-type enzyme, 3 h, completely stable, the first several hours of incubation at 50-70°C help in thermoactivation of the enzyme
70
purified recombinant wild-type enzyme, 3 h, completely stable, half-life is 12 h, the first several hours of incubation at 50-70°C help in thermoactivation of the enzyme
