What is a luciferase vector?
Panomics’ Luciferase Reporter Vectors are designed to monitor transcription factor binding activity in vivo through the use of the standard luciferase assay. Each Luciferase Reporter Vector contains multiple repeats of a specific transcription factor binding element.
Is luciferase a plasmid?
Luciferase-containing plasmids are commonly used to investigate the effect of regulatory elements, such as promoters, enhancers and untranslated regions, or the effect of mutations of these regulatory elements on gene expression.
What type of enzyme is luciferase?
Luciferases are proteins with enzymatic activity that, in the presence of ATP, oxygen, and the appropriate substrate (typically luciferin), catalyze the oxidation of the substrate in a reaction that results in the emission of a photon.
What is the gene code for luciferase?
The luciferase gene was composed of seven exons, coding for 547 amino acids, separated by six introns spanning 1976 bp of genomic DNA. The deduced amino acid sequences of the luciferase gene of N. caucasica showed 98.9% homology to that of the Palearctic species Lampyris noctiluca.
What type of molecule is luciferase?
Luciferase is a generic term for the class of oxidative enzymes that produce bioluminescence, and is usually distinguished from a photoprotein. The name was first used by Raphaël Dubois who invented the words luciferin and luciferase, for the substrate and enzyme, respectively….Luciferase.

Is luciferase a reporter gene?
A commonly used reporter gene is the luciferase gene from the firefly Photinus pyralis. This gene encodes a 61-kDa enzyme that oxidizes D-luciferin in the presence of ATP, oxygen, and Mg(++), yielding a fluorescent product that can be quantified by measuring the released light.
What is the function of luciferase?
How does luciferase enzyme work?
Luciferase enzymes (firefly, Renilla, or Gaussia) expressed in the cytoplasm of engineered cells catalyze production of light photons from the appropriate substrate. Beetle luciferases react with luciferin in a chemical reaction that requires magnesium, oxygen, and ATP.
