DOI: 10.1039/b814566k
A red-emitting luciferase (
max = 615 nm) compares favorably with the commonly used luciferase reporter (max = 557 nm) in monitoring gene expression in vivo and may be particularly suitable for multianalyte assays in vitro and simultaneous monitoring of several molecular events in vivo.
An ancestral luciferase in the Malpighi tubules of a non-bioluminescent beetle!
V. R. Viviani, R. A. Prado, F. C. G. Arnoldi and F. C. Abdalla,
Photochem. Photobiol. Sci., 2009, 8, 57
DOI: 10.1039/b817114a
CCD imaging of mealworms firefly D-luciferin induced chemiluminescence showed that a luciferase-like enzyme is found in the Malpighi tubules. This luciferase-like enzyme, which is 30% identical to beetle luciferases, was cloned from a Malpighi tubules cDNA library. The results suggest that the potential for bioluminescence is very ancient in AMP-ligases and provide a first protoluciferase model.
