Activating Compound
| Activating Compound | Comment | Organism | Structure |
|---|---|---|---|
| KCl | substitution of NaCl by KCl does not significantly alter the dependence of light intensity on salt concentrations | Gaussia princeps |  |
| NaCl | maximum activity at 1.0-1.5 M, a high NaCl concentration enhances luciferase stability to thermal denaturation | Gaussia princeps | |

General Information
| General Information | Comment | Organism |
|---|---|---|
| metabolism | enzyme shows positive cooperativity with coelenterazine, rather due to the kinetic cooperativity conditioned by conformational changes in response to substrate binding than to the presence of two catalytic sites | Gaussia princeps |
