Literature summary for 1.13.12.7 extracted from
- Controversial effect of two methylguanidine-based ionic liquids on firefly luciferase (2012), Photochem. Photobiol. Sci., 11, 828-834.
Activating Compound
| Activating Compound | Comment | Organism | Structure |
|---|---|---|---|
| [1,1,3,3-tetramethylguanidine][lactate] | increase in concentration of [1,1,3,3-tetramethylguanidine][Lac] up to 0.25 M increases enzyme activity, and at concentrations more than 0.25 M enzyme activity is decreased. Optimum temperature and thermal stability studies show more stability of luciferase only in the presence of [1,1,3,3-tetramethylguanidine][Lac] | Photinus pyralis |  |
| [1,1,3,3-tetramethylguanidine][propionate] | in the presence of [1,1,3,3-tetramethylguanidine][propionate], enzyme activities are decreased with an increase in ionic liquid concentration | Photinus pyralis | |
