Abstract
Bioluminescence, the emission of light by living organisms, is a captivating and widespread phenomenon with diverse ecological functions. This comprehensive review explores the biodiversity, mechanisms, ecological roles, and conservation challenges of bioluminescent organisms in Brazil, a country known for its vast and diverse ecosystems. From the enchanting glow of fireflies and glow-in-the-dark mushrooms to the mesmerizing displays of marine dinoflagellates and cnidarians, Brazil showcases a remarkable array of bioluminescent species. Understanding the biochemical mechanisms and enzymes involved in bioluminescence enhances our knowledge of their evolutionary adaptations and ecological functions. However, habitat loss, climate change, and photopollution pose significant threats to these bioluminescent organisms. Conservation measures, interdisciplinary collaborations, and responsible lighting practices are crucial for their survival. Future research should focus on identifying endemic species, studying environmental factors influencing bioluminescence, and developing effective conservation strategies. Through interdisciplinary collaborations, advanced technologies, and increased funding, Brazil can unravel the mysteries of its bioluminescent biodiversity, drive scientific advancements, and ensure the long-term preservation of these captivating organisms.

Photochem Photobiol Sci 2024; 23:997-1010. [PMID: 38693447 DOI: 10.1007/s43630-024-00570-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Accepted: 03/28/2024] [Indexed: 05/03/2024]
Abstract
Firefly luciferases emit yellow-green light and are pH-sensitive, changing the bioluminescence color to red in the presence of heavy metals, acidic pH and high temperatures. These pH and metal-sensitivities have been recently harnessed for intracellular pH indication and toxic metal biosensing. However, whereas the structure of the pH sensor and the metal binding site, which consists mainly of two salt bridges that close the active site (E311/R337 and H310/E354), has been identified, the specific role of residue H310 in pH and metal sensing is still under debate. The Amydetes vivianii firefly luciferase has one of the lowest pH sensitivities among the group of pH-sensitive firefly luciferases, displaying high bioluminescent activity and special spectral selectivity for cadmium and mercury, which makes it a promising analytical reagent. Using site-directed mutagenesis, we have investigated in detail the role of residue H310 on pH and metal sensitivity in this luciferase. Negatively charged residues at position 310 increase the pH sensitivity and metal sensitivity; H310G considerably increases the size of the cavity, severely impacting the activity, H310R closes the cavity, and H310F considerably decreases both pH and metal sensitivities. However, no substitution completely abolished pH and metal sensitivities. The results indicate that the presence of negatively charged and basic side chains at position 310 is important for pH sensitivity and metals coordination, but not essential, indicating that the remaining side chains of E311 and E354 may still coordinate some metals in this site. Furthermore, a metal binding site search predicted that H310 mutations decrease the affinity mainly for Zn, Ni and Hg but less for Cd, and revealed the possible existence of additional binding sites for Zn, Ni and Hg.

Abstract
The bioluminescence system of luminescent beetles has extensive applications in biological imaging, protein labeling and drug screening. To explore wild luciferases with excellent catalytic activity and thermal stability, we cloned the luciferase of Pygoluciola qingyu, one species living in areas of high temperature and with strong bioluminescence, by combining transcriptomic sequencing and reverse transcription polymerase chain reaction (RT-PCR). The total length of luciferase gene is 1638 bp and the luciferase consists 544 amino acids. The recombinant P. qingyu luciferase was produced in vitro and its characteristics were compared with those of eight luciferases from China firefly species and two commercial luciferases. Compared with these luciferases, the P. qingyu luciferase shows the highest luminescence activity at room temperature (about 25-28 ℃) with similar KM value for D-luciferin and ATP to the Photinus pyralis luciferase. The P. qingyu luciferase activity was highest at 35 ℃ and can keep high activity at 30-40 ℃, which suggests the potential of P. qingyu luciferase for in vivo and cell application. Our results provide new insights into P. qingyu luciferase and give a new resource for the application of luciferases.

Effect of pH on the secondary structure and thermostability of beetle luciferases: structural origin of pH-insensitivity. PHOTOCHEMICAL & PHOTOBIOLOGICAL SCIENCES : OFFICIAL JOURNAL OF THE EUROPEAN PHOTOCHEMISTRY ASSOCIATION AND THE EUROPEAN SOCIETY FOR PHOTOBIOLOGY 2023; 22:893-904. [PMID: 36681778 DOI: 10.1007/s43630-022-00360-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Accepted: 12/27/2022] [Indexed: 01/22/2023]
Abstract
Beetle luciferases were classified into three functional groups: (1) pH-sensitive yellow-green-emitting (fireflies) which change the bioluminescence color to red at acidic pH, high temperatures and presence of heavy metals; (2) the pH-insensitive green-yellow-emitting (click beetles, railroad worms and firefly isozymes) which are not affected by these factors, and (3) pH-insensitive red-emitting. Although the pH-sensing site in firefly luciferases was recently identified, it is unclear why some luciferases are pH-insensitive despite the presence of some conserved pH-sensing residues. Through circular dichroism, we compared the secondary structural changes and unfolding temperature of luciferases of representatives of these three groups: (1) pH-sensitive green-yellow-emitting Macrolampis sp2 (Mac) and Amydetes vivianii (Amy) firefly luciferases; (2) the pH-insensitive green-emitting Pyrearinus termitilluminans larval click beetle (Pte) and Aspisoma lineatum (Al2) larval firefly luciferases, and (3) the pH-insensitive red-emitting Phrixotrix hirtus railroadworm (PxRE) luciferase. The most blue-shifted luciferases, independently of pH sensitivity, are thermally more stable at different pHs than the red-shifted ones. The pH-sensitive luciferases undergo increases of α-helices and thermal stability above pH 6. The pH-insensitive Pte luciferase secondary structure remains stable between pH 6 and 8, whereas the Al2 luciferase displays an increase of the β-sheet at pH 8. The PxRE luciferase also displays an increase of α-helices at pH 8. The results indicate that green-yellow emission in beetle luciferases can be attained by: (1) a structurally rigid scaffold which stabilizes a single closed active site conformation in the pH-insensitive luciferases, and (2) active site compaction above pH 7.0 in the more flexible pH-sensitive luciferases.

Genome analysis of Phrixothrix hirtus (Phengodidae) railroad worm shows the expansion of odorant-binding gene families and positive selection on morphogenesis and sex determination genes. Gene X 2022; 850:146917.

Abstract
Among bioluminescent beetles of the Elateroidea superfamily, Phengodidae is the third largest family, with 244 bioluminescent species distributed only in the Americas, but is still the least studied from the phylogenetic and evolutionary points of view. The railroad worm Phrixothrix hirtus is an essential biological model and symbolic species due to its bicolor bioluminescence, being the only organism that produces true red light among bioluminescent terrestrial species. Here, we performed partial genome assembly of P. hirtus, combining short and long reads generated with Illumina sequencing, providing the first source of genomic information and a framework for comparative analyses of the bioluminescent system in Elateroidea. This is the largest genome described in the Elateroidea superfamily, with an estimated size of ∼3.4 Gb, displaying 32 % GC content, and 67 % transposable elements. Comparative genomic analyses showed a positive selection of genes and gene family expansion events of growths and morphogenesis gene products, which could be associated with the atypical anatomical development and morphogenesis found in paedomorphic females and underdeveloped males. We also observed gene family expansion among distinct odorant-binding receptors, which could be associated with the pheromone communication system typical of these beetles, and retrotransposable elements. Common genes putatively regulating bioluminescence production and control, including two luciferase genes corresponding to lateral lanterns green-emitting and head lanterns red-emitting luciferases with 7 exons and 6 introns, and genes potentially involved in luciferin biosynthesis were found, indicating that there are no clear differences about the presence or absence of gene families associated with bioluminescence in Elateroidea.

Abstract
The availability of new bioluminescent proteins with tuned properties, both in terms of emission wavelength, kinetics and protein stability, is highly valuable in the bioanalytical field, with the potential to improve the sensitivity and analytical performance of the currently used methods for ATP detection, whole-cell biosensors, and viability assays among others. We present a new luciferase mutant, called BgLuc, suitable for developing whole-cell biosensors and in vitro biosensors characterized by a bioluminescence maximum of 548 nm, narrow emission bandwidth, favorable kinetic properties, and excellent pH- and thermo-stabilities at 37 and 45 °C and pH from 5.0 to 8.0. We assessed the suitability of this new luciferase for whole-cell biosensing with a cell-based bioreporter assay for Nuclear Factor-kappa B (NF-kB) signal transduction pathway using 2D and 3D human embryonic kidney (HEK293T) cells, and for ATP detection with the purified enzyme. In both cases the luciferase showed suitable for sensitive detection of the target analytes, with better or similar performance than the commercial counterparts.

Bioluminescence Color-Tuning Firefly Luciferases: Engineering and Prospects for Real-Time Intracellular pH Imaging and Heavy Metal Biosensing. BIOSENSORS 2022; 12:bios12060400.

Abstract
Firefly luciferases catalyze the efficient production of yellow-green light under normal physiological conditions, having been extensively used for bioanalytical purposes for over 5 decades. Under acidic conditions, high temperatures and the presence of heavy metals, they produce red light, a property that is called pH-sensitivity or pH-dependency. Despite the demand for physiological intracellular biosensors for pH and heavy metals, firefly luciferase pH and metal sensitivities were considered drawbacks in analytical assays. We first demonstrated that firefly luciferases and their pH and metal sensitivities can be harnessed to estimate intracellular pH variations and toxic metal concentrations through ratiometric analysis. Using Macrolampis sp2 firefly luciferase, the intracellular pH could be ratiometrically estimated in bacteria and then in mammalian cells. The luciferases of Macrolampis sp2 and Cratomorphus distinctus fireflies were also harnessed to ratiometrically estimate zinc, mercury and other toxic metal concentrations in the micromolar range. The temperature was also ratiometrically estimated using firefly luciferases. The identification and engineering of metal-binding sites have allowed the development of novel luciferases that are more specific to certain metals. The luciferase of the Amydetes viviani firefly was selected for its special sensitivity to cadmium and mercury, and for its stability at higher temperatures. These color-tuning luciferases can potentially be used with smartphones for hands-on field analysis of water contamination and biochemistry teaching assays. Thus, firefly luciferases are novel color-tuning sensors for intracellular pH and toxic metals. Furthermore, a single luciferase gene is potentially useful as a dual bioluminescent reporter to simultaneously report intracellular ATP and/or luciferase concentrations luminometrically, and pH or metal concentrations ratiometrically, providing a useful tool for real-time imaging of intracellular dynamics and stress.

Cloning and molecular properties of a novel luciferase from the Brazilian Bicellonycha lividipennis (Lampyridae: Photurinae) firefly: comparison with other firefly luciferases.

Abstract
Several firefly luciferases eliciting light emission in the yellow-green range of the spectrum and with distinct kinetic properties have been already cloned, sequenced, and characterized. Some of them are currently being applied as analytical reagents and reporter genes for bioimaging and biosensors, and more recently as potential color tuning indicators of intracellular pH and toxic metals. They were cloned from the subfamilies Lampyrinae (Photinini: Photinus pyralis, Macrolampis sp2; Cratomorphini: Cratomorphus distinctus), Photurinae (Photuris pennsylvanica), Luciolinae (Luciola cruciata, L. lateralis, L. mingrelica, L. italica, Hotaria parvula), and Amydetinae (Amydetes vivianii) occurring in different parts of the world. The largest number has been cloned from fireflies occurring in Brazilian biomes. Taking advantage of the large biodiversity of fireflies occurring in the Brazilian Atlantic rainforest, here we report the cloning and characterization of a novel luciferase cDNA from the Photurinae subfamily, Bicellonycha lividipennis, which is a very common firefly in marshlands in Brazil. As expected, multialignements and phylogenetic analysis show that this luciferase clusters with Photuris pennsylvanica adult isozyme, and with other adult lantern firefly luciferases, in reasonable agreement with traditional phylogenetic analysis. The luciferase elicits light emission in the yellow-green region, has kinetics properties similar to other adult lantern firefly luciferases, including pH- and metal sensitivities, but displays a lower sensitivity to nickel, which is suggested to be caused by the natural substitution of H310Y.
