Description

General description

D-Luciferin is a small molecule present abundantly in bioluminescent organisms. This molecule is sensitive to oxygen and light.

Application

D-Luciferin has been used in determining luciferase activity by luciferase assay in mice and Arabidopsis thaliana seeds. It has also been used in measuring bioluminescence in neonatal rat ventricular cardiomyocytes.

Substrate for firefly luciferase with a Km of approx 2 μM.

Biochem/physiol Actions

D-Luciferin uptake within the cells is regulated by the adenosine triphosphate (ATP)-binding cassette (ABC) transporter inhibitors like ATP-binding cassette transporter G2 (ABCG2)/ breast cancer resistance protein (BCRP) inhibitor fumitremorgin C. This substrate is oxidized by firefly luciferase that results in emitting a photon, which has the capability of passing through living tissues.
