Thoughts on the diversity of convergent evolution of bioluminescence on earth
(CAMBRIDGE UNIV PRESSNEW YORK, 2012)
The widespread independent evolution of analogous bioluminescent systems is one of the most impressive and diverse examples of convergent evolution on earth. There are roughly 30 extant bioluminescent systems that have ...
Bovine serum albumin displays luciferase-like activity in presence of luciferyl adenylate: Insights on the origin of protoluciferase activity and bioluminescence colours
(2006-07-01)
Luciferyl adenylate, the key intermediate in beetle bioluminescence, is produced through adenylation of D-luciferin by beetle luciferases and also by mealworm luciferase-like enzymes which produce a weak red chemiluminescence. ...
Evidence that a single bioluminescent system is shared by all known bioluminescent fungal lineages
(ROYAL SOC CHEMISTRYCAMBRIDGE, 2012)
Since the early 20th century, many researchers have attempted to determine how fungi are able to emit light. The first successful experiment was obtained using the classical luciferin-luciferase test that consists of mixing ...
Bioluminescence Analysis of Antibacterial Photodynamic Therapy Using Methylene Blue Mediated by Low-Intensity Level Laser Against Cariogenic Biofilms
(Mary Ann Liebert, Inc, 2018-05-01)
Objective: A non-destructive and real-time bioluminescence (BL) assay was used to determine the utility of antimicrobial photodynamic therapy (aPDT) treatments mediated by methylene blue (MB) and laser irradiation (LI) ...
The influence of the region between residues 220 and 344 and beyond in Phrixotrix railroad worm luciferases green and red bioluminescence
(2004-02-01)
To find the regions having a major influence on the bioluminescence spectra of railroad worm luciferases, we constructed new chimeric luciferases switching the fragments from residues 1-219 and from 220-545 between Phrixotrix ...
The structural origin and biological function of pH-sensitivity in firefly luciferases
(2008-02-19)
Firefly luciferases are called pH-sensitive because their bioluminescence spectra display a typical red-shift at acidic pH, higher temperatures, and in the presence of heavy metal cations, whereas other beetle luciferases ...
Active-site properties of Phrixotrix railroad worm green and red bioluminescence-eliciting luciferases
(Japanese Biochemical Soc, 2006-10-01)
The luciferases of the railroad worm Phrixotrix (Coleoptera: Phengodidae) are the only beetle luciferases that naturally produce true red bioluminescence. Previously, we cloned the green- (PxGR) and red-emitting (PxRE) ...
Ex vivo evaluation of intravitreal mesenchymal stromal cell viability using bioluminescence imaging
(BioMed Central, 2018)
Abstract
Background
Bone marrow-derived mesenchymal stromal cell (MSC) therapy is a promising treatment for several degenerative ocular diseases; however, no reproducible ...
Molecular insights on the evolution of the lateral and head lantern luciferases and bioluminescence colors in Mastinocerini railroad-worms (Coleoptera: Phengodidae)
(Royal Soc Chemistry, 2010-01-01)
Among bioluminescent beetles of Elateroidea superfamily, railroad-worms (Phengodidae) produce the widest range of colors, from green to red, using the same luciferin-luciferase system. Members of the Mastinocerini tribe ...
Bixin and lycopene modulation of free radical generation induced by cisplatin-DNA interaction
(ELSEVIER SCI LTD, 2009)
This work evaluated the Modulation of reactive oxygen species (ROS) produced by the cisplatin-human DNA interaction in a cell-free experimental model by the carotenoids bixin and lycopene extracted from, natural dietary ...
