molecular biology | the development of variants of Renilla luciferase, which exhibit significantly improved properties compared with the native enzyme, will allow enhanced sensitivity in existing luciferase-based assays as well as enable the development of novel probes labeled with the luciferase protein | Renilla sp. |

A55T/C124A/S130A/K136R/A143M/M185V/M253L/S287L | mutant enzyme exhibits a greater than 4-fold enhancement in activity, a 200fold increased resistance to serum inactivation, and a small but measurable 5 nm red shift in the emission spectrum. The enhancement in light output arises from a combination of increases in quantum yield and improvedkinetics | Renilla sp. |
M185V/Q235A | compared with the native enzyme the mutant has twice the rate of inactivation, as measured in murine serum, while incorporating a close to 5fold improvement in light output | Renilla sp. |
