Abstract
Different fungi lineages are known to emit light on Earth, mainly in tropical climates. Although the preparation of bioluminescent cell-free extracts allowed one to characterize the enzymatic requirements, the molecular mechanism underlying luminescence is still largely unknown and is based on the experimental putative assumption that a high-energy intermediate should be formed by reaction with O2 and formation of an endoperoxide. Here, we aim at determining, through state-of-the-art multiconfigurational quantum chemistry, the full mechanistic landscape leading from the endoperoxide to the emitting species, envisaging different possible pathways and proposing their viability. Especially, thermal CO2 detachment followed by excited-state peroxide opening (thermal-chemiluminescence) can compete with a parallel pathway, i.e., first excited-state endoperoxide opening, followed by CO2 detachment on the same excited-state (excited state-chemiluminescence). Clear differences in the energy supplies, as well as the possibility to directly populate the emitting species from the intersection seam between ground and excited states, land credence to a kinetically efficient thermal-chemiluminescent pathway, establishing for the first time a detailed description of fungal bioluminescence.

Abstract
Fermentative glycolysis, an ancient evolved metabolic pathway, is exploited by rapidly growing tissues and tumors but also occurs in response to the nutritional and energetic demands of differentiated tissues. The lactic acid it produces is transported across cell membranes through reversible H+/lactate−symporters (MCT1 and MCT4) and is recycled in organs as a major metabolic precursor of gluconeogenesis and an energy source. Concentrations of lactate in the tumor environment, investigated utilizing an induced metabolic bioluminescence imaging (imBI) technique, appear to be dominant biomarkers of tumor response to irradiation and resistance to treatment. Suppression of lactic acid formation by genetic disruption of lactate dehydrogenases A and B in aggressive tumors reactivated OXPHOS (oxidative phosphorylation) to maintain xenograft tumor growth at a halved rate. In contrast, disruption of the lactic acid transporters MCT1/4 suppressed glycolysis, mTORC1, and tumor growth as a result of intracellular acidosis. Furthermore, the global reduction of tumor acidity contributes to activation of the antitumor immune responses, offering hope for future clinical applications.

Abstract
The major obstacles to the wider application of photodynamic therapy (PDT) are drawbacks of the current photosensitizers and the tissue penetration limit of the common outer light source. In the present study, the chemiluminescence (CL) from the luminol-H2O2-horseradish peroxidase reaction was explored as a potential inner light source for the intracellular activation of carbon dots (CDs)-based PDT system. To fully use the light and enhance the overall PDT yield, the nanocarrier of CDs, the light of CL, and the PDT agent chlorin e6 (Ce6) were carefully selected and designed to form an efficient and united system. Bright-yellow-emissive CDs (y-CDs) were synthesized through purposeful regulation of the absorption and emission spectra to enhance the overlapping areas in the chemiluminescence resonance energy transfer (CRET) and fluorescence resonance energy transfer (FRET) processes. Our results reflected CL-induced y-CDs-Ce6 system (10 μM) successfully generated reactive oxygen species (ROS, 35.93%), killed ∼90% SMMC-7721 cells in vitro, and significantly delayed tumor growth in vivo. On the basis of immunohistochemical observations of proliferating cell nuclear antigen (PCNA) and platelet/endothelial cell adhesion molecule-1 (PECAM-1 or CD31) results, we concluded that the CL-induced y-CDs-Ce6 system had excellent performance in cancer therapy. The enhanced therapeutic effect was ascribed to two pathways: a direct CRET process and another process of CRET with subsequent y-CD-mediated FRET (CRET-to-FRET).

Abstract
Firefly luciferase as a bioluminescent enzyme has many applications in various fields from scientific research to commercial goals. This enzyme is relatively unstable with low functional capacity due to rapid inactivation in physiological temperature, low in vitro stability and high susceptibility to proteolytic degradation. Based on previous studies, two regions 206-220 and 329-341 on N-domain of Photinus pyralis luciferase are known accessible and flexible. Flexible regions may lead to protein instability. Here, the effect of mutation at positively charged residues Lys(K)329 and Arg(R)330 on the stability of luciferase was studied. Furthermore, the role of these mutations on the structure and function was evaluated. Introducing of these point mutations did not affect the orientation of critical residues in bioluminescence color determination. The kinetic studies showed that thermostability and Km value for luciferin in both mutants were decreased as compared to wild type. However, optimum pH and optimum temperature showed no significant changes in both mutants. Moreover, the structural data revealed an increase in tryptophan fluorescence intensity and secondary structure content for R330Q in compared with wild type, while intrinsic fluorescence and far-UV CD intensity in K329I mutant was decreased.

Abstract
The emitted color in fireflies’ bioluminescent systems depends on the beetle species the system is extracted from and on different external factors (pH, temperature…) among others. Controlling the energy of the emitted light (i.e., color) is of crucial interest for the use of such bioluminescent systems. For instance, in the biomedical field, red emitted light is desirable because of its larger tissue penetration and lower energies. In order to investigate the influence of the protein environment and the AMP protonation state on the emitted color, the emission spectra of the phenolate-keto and phenolate-enol oxyluciferin forms have been simulated by means of MD simulations and QM/MM calculations, considering: two different protein conformations (with an open or closed C-terminal domain with respect to the N-terminal) and two protonation states of AMP. The results show that the emission spectra when considering the protein characterized by a closed conformation are blue-shifted compared to the open conformation. Moreover, the complete deprotonation of AMP phosphate group (AMP2−) can also lead to a blue-shift of the emission spectra but only when considering the closed protein conformation (open form is not sensitive to changes of AMP protonation state). These findings can be reasoned by the different interactions (hydrogen-bonds) found between oxyluciferin and the surrounding (protein, AMP and water molecules). This study gets partial insight into the possible origin of the emitted color modulation by changes of the pH or luciferase conformations.

Abstract
: The latest advances in molecular biology have made available several biotechnological tools that take advantage of the high detectability and quantum efficiency of bioluminescence (BL), with an ever-increasing number of novel applications in environmental, pharmaceutical, food, and forensic fields. Indeed, BL proteins are being used to develop ultrasensitive binding assays and cell-based assays, thanks to their high detectability and to the availability of highly sensitive BL instruments. The appealing aspect of molecular biology tools relying on BL reactions is their general applicability in both in vitro assays, such as cell cultures or purified proteins, and in vivo settings, such as in whole-animal BL imaging. The aim of this chapter is to provide the reader with an overview of state-of-the-art bioluminescent tools based on luciferase genes, highlighting molecular biology strategies that have been applied so far, together with some selected examples.

Abstract
An ultrasensitive and rapid sandwich-type chemiluminescence immunoassay (CLIA) was developed for the clinical determination of human epididymis protein 4 (HE4) in human serum, using GoldMag nanoparticles as solid phase and acridinium ester (AE) as chemiluminescence system (GMP-CLIA). The process of AE labeling antibodies was systematically studied and evaluated. The effect of varies factors such as molar ratio of AE to antibodies, labeling time, and the components of elution buffer and trigger solution were optimized. Under the selected conditions, AE labeling experiments were successfully performed with the average labeling efficiency of 1.92 ± 0.08, and antibody utilization rate of 69.77 ± 1.19%. Antibody activity remained unchanged after labeling. The established GMP-CLIA method can detect HE4 in the range of 0.25–50 ng·mL−1 (10–2000 pM) with a detection limit of 0.084 ng·mL−1 (3.36 pM). The sensitivity has reached a high level, comparable with the current commercial detection kits. This proposed method has been successfully applied to the clinical determination of HE4 in 65 human sera. The results showed a good correlation with a clinical method, microplate-based chemiluminescence enzyme immunoassay (CLEIA), with the correlation coefficient of 0.9594.

Abstract
The technique of induced metabolic bioluminescence imaging (imBI) has been developed to obtain a "snapshot" of the momentary metabolic status of biological tissues. Using cryosections of snap-frozen tissue specimens, imBI combines highly specific and sensitive in situ detection of metabolites with a spatial resolution on a microscopic level and with metabolic imaging in relation to tissue histology. Here, we present the application of imBI in human colorectal cancer. Comparing the metabolic information of one biopsy with that of 2 or 3 biopsies per individual cancer, the classification into high versus low lactate tumors, reflecting different glycolytic activities, based on a single biopsy was in agreement with the result from multiple biopsies in 83 % of all cases. We further demonstrate that the metabolic status of tumor tissue can be preserved at least over 10 years by storage in liquid nitrogen, but not by storage at -80 °C. This means that tissue banking with long-term preservation of the metabolic status is possible at -180 °C, which may be relevant for studies on long-term survival of cancer patients. As with other tumor entities, tissue lactate concentration was shown to be correlated with tumor development and progression in colorectal cancer. At first-time diagnosis, lactate values were low in rectal normal tissue and adenomas, were significantly elevated to intermediate levels in non-metastatic adenocarcinomas, and were very high in carcinomas with distant metastasis. There was an inverse behavior of tissue glucose concentration under corresponding conditions. The expression level of monocarboxylate transporter-4 (MCT4) was positively correlated with the tumor lactate concentration and may thus contribute to high lactate tumors being associated with a high degree of malignancy.

Abstract
Ionic liquids as neoteric solvents, microwave irradiation, and alternative energy source are becoming as a solvent for many enzymatic reactions. We recently showed that the incubation of firefly luciferase from Photinus pyralis with various ionic liquids increased the activity and stability of luciferase. Magnetic nanoparticles supported ionic liquids have been obtained by covalent bonding of ionic liquids-silane on magnetic silica nanoparticles. In the present study, the effects of [γ-Fe2O3@SiO2][BMImCl] and [γ-Fe2O3@SiO2][BMImI] were investigated on the structural properties and function of luciferase using circular dichroism, fluorescence spectroscopy, and bioluminescence assay. Enzyme activity and structural stability increased in the presence of magnetic nanoparticles supported ionic liquids. Furthermore, the effect of ingredients which were used was not considerable on K(m) value of luciferase for adenosine-5'-triphosphate and also K(m) value for luciferin.

Abstract
The first systematic pico-nanosecond time-resolved spectroscopic study of the firefly emitter oxyluciferin and two of its chemically modified analogues revealed that in the excited state the enol group is more acidic than the phenol group. The 6'-dehydroxylated derivative, in which only the 4-enolic hydroxyl proton is acidic, has an experimentally determined pK(a)* of 0.9 in dimethyl sulfoxide and an estimated pK(a)* of -0.3 in water. Moreover, this compound provided direct evidence that in a nonpolar, basic environment the keto form in the excited state can tautomerize into the enol, which subsequently undergoes excited-state proton transfer (ESPT) to produce enolate ion. This observation presents the first experimental evidence of excited-state keto-enol tautomerization of a firefly fluorophore, and it could be important in resolving the enol-keto conundrum related to the color-tuning mechanism of firefly bioluminescence. The 6'-dehydroxylated form of oxyluciferin adds a very rare case of a stable enol to the family of "super"photoacids.

Abstract
The effects of environmental polarity on the enolization of the keto form and the deprotonation of the enol, and the role of the neutral and ionized 6'-OH group in the fluorescence of the firefly emitter, oxyluciferin, were assessed through a detailed study of the structure and absorption and fluorescence spectra of its 6'-dehydroxylated analogue. It was found that the deprotonated 6'-O(-) group is a necessary, albeit insufficient, factor in accounting for the observed yellow-green and red emissions of oxyluciferin. Its negative charge is essential for effective excited-state charge transfer, which lowers the emission energy and broadens the emission spectrum. Deprotonation of the 6'-OH group changes its effect on the emission energy from blue- to red-shifting. Furthermore, the combination of these opposite effects and resonance stabilization of the phenolate-keto form causes switching of the order of maximum emission wavelengths of the three species involved in the keto-enol-enolate equilibrium from enol << keto < enolate in absence of 6'-OH to keto < enol << enolate with 6'-OH, to enol < enolate < keto with 6'-O(-). If only the keto-enol-enolate equilibrium is considered, solvents of medium polarity are the most effective in decreasing the excited-state energy. Polar or very polar environments also stimulate shift of the ground-state equilibrium toward the enol form. Under such circumstances, the enol group can be partly or completely deprotonated in the ground state or from the excited state: a polar environment facilitates the ionization, while a less polar environment requires the presence of a stronger base. In the absence of bases, the ground-state keto form exists only in solvents of very weak to medium polarity, but with stronger bases, it can also exist in a nonpolar or very weakly polar environment, usually together with the enolate anion. The phenol-enolate form of oxyluciferin, a species that could not be experimentally detected prior to this study, was identified as a yellow-emitting species.

Abstract
Serum thyroglobulin (Tg) is a main marker of thyroid cancer relapses after total or near-total thyroidectomy of patients with differentiated thyroid carcinoma. In this study, we developed a chemiluminescent enzyme-linked immunosorbent assay (CL-ELISA) for detecting Tg in human serum. Soybean peroxidase (SbP) in combination with 3-(10'-phenothiazinyl)propane-1-sulfonate (SPTZ) and 4-morpholinopyridine (MORPH) and horseradish peroxidase (HRP) with p-iodophenol (PIP) were used as detection systems in the sandwich CL-ELISA. Comparison of these two systems showed that a lower detection limit (LOD) of CL-ELISA with SbP/SPTZ/MORPH was 10 times lower than for the immunoassay with HRP/PIP. The LOD value for SbP-based CL-ELISA of 0.2 ng/mL was identical to LOD value typical of CL-ELISA Immulite kit produced with alkaline phosphatase. The sensitivity of Tg CL-ELISA using SbP/SPTZ/MORPH completely satisfies the requirements of modern endocrinology. Comparative study of clinical serum specimens assayed by the SbP-based CL-ELISA (x) and Immulite kit (y) for detecting Tg showed a good correlation between these two immunoassays (y=1.15 x -0.14, R=0.99). The obtained results open good perspectives for use of SbP/SPTZ/MORPH system in the development of ultra-sensitive immunoassays.

Abstract
Background Enzymes belonging to acyl:CoA synthetase (ACS) superfamily activate wide variety of substrates and play major role in increasing the structural and functional diversity of various secondary metabolites in microbes and plants. However, due to the large sequence divergence within the superfamily, it is difficult to predict their substrate preference by annotation transfer from the closest homolog. Therefore, a large number of ACS sequences present in public databases lack any functional annotation at the level of substrate specificity. Recently, several examples have been reported where the enzymes showing high sequence similarity to luciferases or coumarate:CoA ligases have been surprisingly found to activate fatty acyl substrates in experimental studies. In this work, we have investigated the relationship between the substrate specificity of ACS and their sequence/structural features, and developed a novel computational protocol for in silico assignment of substrate preference. Results We have used a knowledge-based approach which involves compilation of substrate specificity information for various experimentally characterized ACS and derivation of profile HMMs for each subfamily. These HMM profiles can accurately differentiate probable cognate substrates from non-cognate possibilities with high specificity (Sp) and sensitivity (Sn) (Sn = 0.91-1.0, Sp = 0.96-1.0) values. Using homologous crystal structures, we identified a limited number of contact residues crucial for substrate recognition i.e. specificity determining residues (SDRs). Patterns of SDRs from different subfamilies have been used to derive predictive rules for correlating them to substrate preference. The power of the SDR approach has been demonstrated by correct prediction of substrates for enzymes which show apparently anomalous substrate preference. Furthermore, molecular modeling of the substrates in the active site has been carried out to understand the structural basis of substrate selection. A web based prediction tool http://www.nii.res.in/pred_acs_substr.html has been developed for automated functional classification of ACS enzymes. Conclusions We have developed a novel computational protocol for predicting substrate preference for ACS superfamily of enzymes using a limited number of SDRs. Using this approach substrate preference can be assigned to a large number of ACS enzymes present in various genomes. It can potentially help in rational design of novel proteins with altered substrate specificities.

Abstract
The decomposition of peroxymonocarbonate (HCO(4)(-)) has been investigated by flow-injection chemiluminescence (CL) method. An ultraweak CL was observed during mixing the bicarbonate and hydrogen peroxide solution in organic cosolvent. An appropriate amount of fluorescent organic compounds, such as dichlorofluorescein (DCF), was added to the HCO(4)(-) solution, a strong CL was recorded. Based on studies of the spectrum of fluorescence, CL and UV-vis spectra, electron spin trapping (ESR) technique, mass spectra (MS) and comparison with H(2)O(2)/hypochlorite (ClO(-)) and H(2)O(2)/molybdate (MoO(4)(-)) systems, the CL mechanism was proposed. The reaction is initiated by unimolecular homolysis of the peroxo O-O bond in HO-OCOO(-) molecule. It was suggested that the bond rearrangement within radicals yield superoxide ion (O(2)(*-)). The interaction of superoxide ion with perhydroxyl radical produces singlet oxygen ((1)O(2)). The energy transfers from singlet oxygen to DCF forming an excited energy acceptor (DCF*). Luminescence (lambda(max)=509 nm) was emitted during the relaxation of the energy acceptor to the ground state.

Abstract
The yellow-green luminescence from firefly luciferase has long been understood to be the emission from enol-oxyluciferin. However, a recent experiment showed that an oxyluciferin constrained to the keto form produced a yellow-green emission in luciferase (Branchini, B. R.; Murtiashaw, M. H.; Magyar, R. A.; Portier, N. C.; Ruggiero, M. C.; Stroh, J. G. J. Am. Chem. Soc. 2002, 124, 2112-2113). The present quantum mechanical/molecular mechanical and symmetry-adapted cluster-configuration interaction (SAC-CI) theoretical study supports the keto-form to be the yellow-green bioluminescence state in luciferase. We give the theoretically optimized structure of the excited state of oxyluciferin within luciferase, which gives luminescence calculated by the SAC-CI method that is close to the experimental value. Coulombic interactions with neighboring residues, in particular Arg218 and the phosphate group of AMP, play important roles in the color-tuning mechanism. Transformation to the enol form is energetically unfavorable in the luciferase environment. The twisted intramolecular charge-transfer (TICT) state is meta stable and would be easily relaxed to the co-planer structure. Further analyses were performed to verify the spectral-tuning mechanism based on the protonation state and the resonance structure of oxyluciferin.

Abstract
Previously we combined common practices in protein detection with chemiluminescence, microwave technology, and metal-enhanced chemiluminescence to demonstrate that we can use low power microwaves to substantially increase enzymatic chemiluminescent reaction rates on particulate silvered substrates. We now describe the applicability of continuous aluminum metal substrates to potentially further enhance or "trigger" enzymatic chemiluminescence reactions. Furthermore, our results suggest that the extent of chemiluminescence enhancement for surface and solution based enzyme reactions critically depends on the surface geometry of the aluminum film. In addition, we also use FDTD simulations to model the interactions of the incident microwave radiation with the aluminum geometries used. We demonstrate that the extent of microwave field enhancement for solution and surface based chemiluminescent reactions can be ascribed to "lightning rod" effects that give rise to different electric field distributions for microwaves incident on planar aluminum geometries. With these results, we believe that we can spatially and temporally control the extent of triggered chemiluminescence with low power microwave (Mw) pulses and maximize localized microwave triggered metal-enhanced chemiluminescence (MT-MEC) with optimized planar aluminum geometries. Thus we can potentially further improve the sensitivity of immunoassays with significantly enhanced signal-to-noise ratios.

Abstract
A selective lysis of relatively young erythrocytes (neocytolysis), together with a decrease of erythropoietin (EPO) production, has been described in polycythemic, high altitude acclimatized climbers, after descent to sea level, and in astronauts, soon after exposure to weightlessness (Alfrey CP, Rice L, Udden MM, Driscoll TB. Neocytolysis may represent the physiological down-regulation of red-cell mass. Lancet 349 (1997) 1389-90). To study neocytolysis, we analysed blood samples drawn from 4 mountain climbers at sea level before and after 53 days of high altitude acclimatization (> or = 4500 m). After a 6-day descent to sea level, erythropoietin (EPO) plasma levels were lower than before high altitude acclimatization (mean values: 2.5+/-3.3 versus 10+/-4.5 mIU/ml, p < 0.05). Red blood cell (RBC) populations were separated into low, middle and high density subsets, which, by physical and phenotypical criteria, were characterized as young, middle-aged and old. RBC membrane molecules CD55 and CD59 along with phosphatydylserine and CD47 were measured. The former are partially lost during RBC aging. The latter are involved in the triggering or inhibition of RBC phagocytosis by macrophages. Immunofluorescence and flow cytometry were done on each density subset. Young and middle-aged RBCs largely disappeared after descent from high altitude (from 4.50% (+/-3.10) and 66% (+/-6.90) to 0.19% (+/-0.07) and 1.90% (+/-0.50), respectively). Simultaneously, there was a dramatic increase of high density RBCs (from 29.50% (+/-7) to 97.90% (+/-2.00)). Furthermore, the remaining young and middle-aged RBCs had acquired a senescent-like phenotype, which may account for their increased susceptibility to phagocytosis.

Abstract
The effective new variant of "sandwich" bioluminescent enzyme immunoassay (BEIA) for the sensitive detection of glycoprotein B (gB) of pseudorabies virus (PrV) was presently developed. The high affinity interaction of barnase-barstar protein pair and photoprotein obelin as bioluminescent marker were for the first time successfully applied to BEIA development. Preliminary the two monoclonal antibodies, 11/5 and 34/2, were raised against gB for ELISA PrV detection. Presently we used the same immuno-"sandwich" principle for BEIA. To do this the two different bioconjugates were elaborated. Recombinant barnase was chemically conjugated with monoclonal anti-PrV's gB IgG, and also barstar was fused in frame to obelin. The characteristics of BEIA method have been compared to ELISA PrV detection. We have shown the proposed here gB-BEIA was 40-fold more sensitive as opposed to gB-ELISA test. The construction might have a broad promise in multiple potential immunological applications.

Abstract
In this review I will discuss chemical principles of the luminescence of imidazo[1,2-a]pyrazin-3(7H)-one compounds described to date. The review is composed of two main parts, the first dealing with the bioluminescence of coelenterate luciferin "coelenterazine" and Cypridina luciferin in marine organisms and the second with the chemiluminescence of these luciferins and their analogues. In the second section, possible applications of chemiluminescence and enhanced chemiluminescence in the area of bioassay are also discussed.

Abstract
Light emission from the North American firefly Photinus pyralis, which emits yellow-green (557-nm) light, is widely believed to be the most efficient bioluminescence system known, making this luciferase an excellent tool for monitoring gene expression. We present studies on the production of a set of thermostable red- and green-emitting luciferase mutants with bioluminescent properties suitable for dual-color reporter assays, biosensor measurements with internal controls, and imaging techniques. Starting with the luciferase variant Ser284Thr, we introduced the mutations Thr214Ala, Ala215Leu, Ile232Ala, Phe295Leu, and Glu354Lys to produce a new red-emitting enzyme with a bioluminescence maximum of 610 nm, narrow emission bandwidth, favorable kinetic properties, and excellent thermostability at 37 degrees C. By adding the same five changes to luciferase mutant Val241Ile/Gly246Ala/Phe250Ser, we produced a protein with an emission maximum of 546 nm, providing a set of thermostable enzymes whose bioluminescence maxima were separated by 64 nm. Model studies established that the luciferases could be detected at the attomole level and six orders of magnitude higher. In microplate luminometer format, mixtures containing 1.0 fmol total luciferase were quantified from measurements of simultaneously emitted red and green light. The results presented here provide evidence that it is feasible to monitor two distinct activities at 37 degrees C with these novel thermostable proteins.

Abstract
Photodynamic therapy (PDT) involves a two-stage process. A light-absorbing photosensitiser (Ps) is endocytosed and then stimulated by light, inducing transfer of energy to a cytoplasmic acceptor molecule and the generation of reactive oxygen species that initiate damage to cellular membrane components and cytolysis. The expanded use of PDT in the clinic is hindered by the lack of Ps target-cell specificity and the limited tissue penetration by external light radiation. This study demonstrates that bioconjugates composed of transferrin and haematoporphyrin (Tf–Hp), significantly improve the specificity and efficiency of PDT for erythroleukemic cells by a factor of almost seven-fold. Fluorescence microscopy showed that the conjugates accumulate in intracellular vesicles whereas free Hp was mostly membrane bound. Experiments with cells deliberately exposed to Tf–Hp at <LD100 doses showed that surviving cells did not develop resistance to subsequent treatments with the conjugate. Furthermore, we show that the compound luminol induces intracellular chemiluminescence. This strategy was then used to obviate the use of external radiation for Ps activation by incubating the cells with luminol either before or together with Tf–Hp. This novel chemical means of PDT activation induced cytotoxicity in 95% of cells. These combined approaches provide an opportunity to develop broader and more effective applications of PDT.

Abstract
Bioluminescence spectra of the wild-type recombinant Luciola mingrelica firefly luciferase and its mutant form with the His433Tyr point mutation were obtained within the pH 5.6-10.2 interval. The spectra are shown to be a superposition of the spectra of the three forms of the electronically excited reaction product oxyluciferin: ketone (lambdamax = 618 nm), enol (lambdamax = 587 nm), and enolate-ion (lambdamax = 556 nm). The shift in lambdamax by 40 nm to the red region in the mutant luciferase bioluminescence at the pH optimum of enzyme activity (pH 7.8) is explained by the change in the relative content of different oxyluciferin forms due to the shift in the ketone <--> enol <--> enolate equilibria. A computer model of the luciferase-oxyluciferin-AMP complex was constructed and the structure of amino acid residues participating in the equilibrium is proposed. Computer models of the protein region near the His433 residue for the wild type and mutant luciferases are also proposed. Comparison of the models shows that the His433Tyr mutation increases flexibility of the polypeptide loop that binds the N and C domains of luciferase. As a result, the flexibility of the C domain amino acid residues in the emitter microenvironment increases, and this increase may be the reason for the observed differences in the bioluminescence spectra of the native and mutant luciferases.

Abstract
Coelenterazine and derivatives were initially considered in the scientific community for their (bio)luminescent properties. Now, another interest of such hetero-bicycles has been pointed out by the discovery of remarkable antioxidative properties, and an unique mode of action as a "cascade": the mother-compound (imidazolopyrazinone) is transformed by ROS into a daughter-compound (2-amino-pyrazine) also endowed with antioxidative properties. This review illustrates the therapeutic potential of synthetic imidazolopyrazinones (coelenterazine analogues): chemical reactivity assays with singulet oxygen, radical anion superoxide, peroxynitrite, and radicals formed during lipid and LDL peroxidation, cellular tests of protection against oxidative stress using keratinocyte, hepatocyte, neuronal and erythrocyte cells, and finally in vivo evaluation in a hamster model of ischemia-reperfusion, are fully described.

Abstract
Reaction mechanisms for the formation of the keto-form of oxyluciferin (OxyLH(2)) from the luciferin of fireflies via a dioxetanone intermediate are predicted using the B3LYP/6-31G theoretical method. The ring opening of a model dioxetanone and the decarboxylation proceed in one step via a singlet diradical transition structure with an activation barrier of 18.1 and an exothermicity of 90.8 kcal/mol. The S(0) --> S(1) vertical excitation energies predicted with time dependent density functional theory, TDDFT B3LYP/6-31+G, for the anionic and neutral forms of OxyLH(2) are in the range of 60 to 80 kcal/mol. These energetic results support the generally accepted theory of chemically initiated electron exchange luminescence (CIEEL). The chemical origin of the multicolor bioluminescence from OxyLH(2) is examined theoretically using the TDDFT B3LYP/6-31+G, ZINDO//B3LYP/6-31+G, and CIS/6-31G methods. A change in color of the light emission upon rotation of the two rings in the S(1) excited state of OxyLH(2) is unlikely because both possible emitters, the planar keto- and enol-forms, are minima on the S(1) potential energy surface. The participation of the enol-forms of OxyLH(2) in bioluminescence is plausible but not required to explain the multicolor emission. According to predictions at the TDDFT B3LYP level, the color of the bioluminescence depends on the polarization of the OxyLH(2) in the microenvironment of the enzyme-OxyLH(2) complex.

Abstract
The ZstatFlu-II test is a highly sensitive, specific, rapid, point-of-care chemiluminescent diagnostic test for influenza infection. Influenza viral neuraminidase-specific substrate, spiroadamantyl-1,2-dioxetane-4,7-dimethoxy-N-acetyl-neuraminic acid, is at the core of the ZstatFlu-II Test. The enzymatic reaction was carried out at 25 degrees C and neutral pH, representing the optimum assay conditions for influenza types A and B viral neuraminidases. The results were outputted on a Polaroid trade mark High Speed Detector Film. Positive results appeared as a '+'-shaped white film image; negative results produced no image. The 'glow' kinetics, facilitated by a unique combination of light enhancers, also 'tuned' the wavelength of emission to match the spectral properties of the film. The substrate hydrolysed non-enzymatically at acid pH or at temperatures above 25 degrees C. In order to minimize false positives, the ZstatFlu-II Test was formatted with 0.3-0.4 K(m) substrate and freezing the test kit until use. The pH optimization of the ZstatFlu-II test is discussed with reference to model compounds of sialyl-glycosides. A nucleophilic attack or an electrostatic stabilization of a developing carbonium ion under the influence of the adjacent carboxyl group was probably responsible for non-enzymatic hydrolysis of the substrate. Intramolecular general acid catalysis is proposed as a mechanism for the lability of the O-glycosidic linkage of the substrate.
