Recombinant firefly Luciferase protein
Luciferase is a generic term for the class of oxidative enzymes used in bioluminescence and is distinct from a photoprotein. Luciferase catalyzes a bioluminescent reaction which requires the substrate luciferin as well as Mg2+ and ATP, produces green light with a wavelength of 562 nm. Luciferase from firefly is widely used as a reporter for studying gene regulation and function, and for pharmaceutical screening. Recombinant firefly Luciferase, fused to His-tag at N-terminus, was expressed in E. coli and purified by using conventional chromatography techniques.
