20 h, 53% loss of activity. 32 h, 72% loss of activity | Geobacillus sp. |
70 | - |
the alpha-helix, where notable metal binding and catalytic residues are located, is totally weakened at temperatures above 70°C and thus results in loss of activity. The loss of the alpha-helical structure can explain drastic deterioration of activity at temperatures beyond 70°C | Geobacillus sp. |
