Application

EC Number Application Comment Organism
1.13.12.5 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.

1.13.12.5 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.
1.13.12.5 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.
