LITERATURE
-10 - 35
-
at MgCl concentrations below 0.5 M or CaCl concentrations below 0.35 M, the stability of the protein increases with decreasing temperature down to -10°C. At higher concentrations (0.8-1.5 M MgCl2 or 0.5-1.0 M CaCl2), the curves are bell-shaped with symmetric decreases in stability around 4°C
10 - 45
-
the parasite enzyme activity is not affected in a broad temperature range (from 10°C to 45°C), the enzyme is also stable at 20°C and 37°C over a 30 min period
101
half-life: more than 80 min. Marked stabilizing effect of 1 M K2HPO4 with an increase in thermostability of approximately 40% at 101°C
102
half-life: 30 min
103
half-life: 18 min
20
stable for at least 30 min
30 - 100
high thermal stability of TtMDH, that does not reach a completely denatured state even at near 100°C
30 - 60
the purified recombinant His6-tagged MDH from strain 20Z fully retains activity after 18 h exposure at 30-40°C, and has a 10% residual activity after 18 h exposure at 50°C. The enzyme loses 50% of its activity after 10 min heating at 60°C
30 - 70
-
the enzyme is active in a broader temperature range. It retains full activity after 18 h exposure at 30-60°C, exhibiting a 1 h half-life time at 70°C
37
stable for at least 30 min

-
retains 100% activity after 45 min incubation, only 50% activity remains after 15 min at 45°C
