Ring-Fused Firefly Luciferins: Expanded Palette of Near-Infrared Emitting Bioluminescent Substrates

, 2020
Firefly bioluminescence is broadly applied as a noninvasive imaging modality in the biomedical research field. One limitation in firefly bioluminescence imaging is the limited variety of luciferins emitting in the near-infrared (NIR) region (650–900 nm),

Influence of oxygen, dehydroluciferin, luciferin and 6′-ethyl-luciferin on the synthesis of adenosine (5′) tetraphospho (5′) adenosine (Ap4A) by firefly luciferase

, 2013
The production of light and the synthesis of adenosine (5') tetraphospho (5') adenosine (Ap4A) by firefly luciferase (EC 1.13.12.7) follow different kinetic parameters.

Binding of Luciferin to Firefly Luciferase

, 1993
Program year: 1992/1993Digitized from print original stored in HDRFirefly luciferase catalyzes a bioluminescent oxidation of luciferin. During the first step of the reaction, when luciferin interacts with ATP, a molecule of luciferyl adenylate is formed ...
