Substrate cooperativity in marine luciferases. [PDF]

open access: yesPLoS ONE, 2012
Marine luciferases are increasingly used as reporters to study gene regulation. These luciferases have utility in bioluminescent assay development, although little has been reported on their catalytic properties in response to substrate concentration ...

A puzzling homology: a brittle star using a putative cnidarian-type luciferase for bioluminescence [PDF]

open access: yesOpen Biology, 2017
Bioluminescence relies on the oxidation of a luciferin substrate catalysed by a luciferase enzyme. Luciferins and luciferases are generic terms used to describe a large variety of substrates and enzymes.

Leaving the Dark Side? Insights Into the Evolution of Luciferases

open access: yesFrontiers in Marine Science, 2021
Bioluminescence—i.e., the emission of visible light by living organisms—is defined as a biochemical reaction involving, at least, a luciferin substrate, an oxygen derivative, and a specialised luciferase enzyme.

Luciferase‐free Luciferin Electrochemiluminescence

open access: yesAngewandte Chemie International Edition, 2022
AbstractLuciferin is one of Nature's most widespread luminophores, and enzymes that catalyze luciferin luminescence are the basis of successful commercial “glow” assays for gene expression and metabolic ATP formation. Herein we report an electrochemical method to promote firefly's luciferin luminescence in the absence of its natural biocatalyst ...

Luciferase Controlled Protein Interactions

open access: yesJournal of the American Chemical Society, 2021
Protein trafficking and protein-protein interactions (PPI) are central to regulatory processes in cells. Induced dimerization systems have been developed to control PPI and regulate protein trafficking (localization) or interactions. Chemically induced dimerization (CID) has proven to be a robust approach to control protein interactions and ...

Expanding luciferase reporter systems for cell-free protein expression

open access: yesScientific Reports, 2022
Luciferases are often used as a sensitive, versatile reporter in cell-free transcription-translation (TXTL) systems, for research and practical applications such as engineering genetic parts, validating genetic circuits, and biosensor outputs. Currently,

Localization of the Catalytic Domain of Copepod Luciferases: Analysis of Truncated Mutants of the Metridia longa Luciferase

open access: yesLife, 2023
Luciferases from copepods Metridia longa and Gaussia princeps are successfully used as bioluminescent reporters for in vivo and in vitro assays. Here, we report the minimal sequence of copepod luciferases required for bioluminescence activity that was ...
