The Chemical Basis of Fungal Bioluminescence / K. V. Purtov [et al.] // Angew. Chem. Int. Ed. - 2015. - Vol. 54, Is. 28. - P8124-8128, DOI 10.1002/anie.201501779 . - ISSN 1433-7851

Аннотация: Many species of fungi naturally produce light, a phenomenon known as bioluminescence, however, the fungal substrates used in the chemical reactions that produce light have not been reported. We identified the fungal compound luciferin 3-hydroxyhispidin, which is biosynthesized by oxidation of the precursor hispidin, a known fungal and plant secondary metabolite. The fungal luciferin does not share structural similarity with the other eight known luciferins. Furthermore, it was shown that 3-hydroxyhispidin leads to bioluminescence in extracts from four diverse genera of luminous fungi, thus suggesting a common biochemical mechanism for fungal bioluminescence. © 2015 WILEY-VCH Verlag GmbH & Co.

Why does the bioluminescent fungus Armillaria mellea have luminous mycelium but nonluminous fruiting body? / K. V. Purtov [et al.] // Doklad. Biochem. Biophys. - 2017. - Vol. 474, Is. 1. - P217-219, DOI 10.1134/S1607672917030176 . - ISSN 1607-6729
Аннотация: By determining the components involved in the bioluminescence process in luminous and nonluminous organs of the honey fungus Armillaria mellea, we have established causes of partial luminescence of this fungus. The complete set of enzymes and substrates required for bioluminescence is formed only in the mycelium and only under the conditions of free oxygen access. Since the synthesis of luciferin precursor (hispidin) and 3-hydroxyhispidin hydroxylase in the fruiting bodies is blocked, the formation of luciferin—the key component of fungal bioluminescent system—was not observed. That is why the fruiting body of Armillaria mellea is nonluminous despite the presence of luciferase, the enzyme that catalyzes the oxidation of luciferin with a photon emission. © 2017, Pleiades Publishing, Ltd.

Аннотация: In in vitro experiments, the possibility of using a luminescent system extracted from the luminous fungus Armillaria borealis has been shown to detect and determine the concentration of hispidin. A linear dependence of the luminescent response on the content of hispidin in solutions in the concentration range of 5.4 x 10(-5) - 1.4 x 10(-2) mu M was detected. The stability of the enzyme system and the high sensitivity of the bioluminescent reaction allows carrying out multiple measurements with the analyte detection limit of 1.3 x 10(-11) g. The obtained results show the prospects of creating a rapid bioluminescent method for the analysis of medical substances or extracts from various biological objects for the presence of hispidin.

Two forms of substrate for the bioluminescent reaction in three species of basidiomycetes / A. P. Puzyr [et al.] // Mycol. - 2019. - Vol. 10, Is. 2. - P84-91, DOI 10.1080/21501203.2019.1583688 . - ISSN 2150-1203

Cold and hot extracts -- culture liquid -- enzymatic system -- hispidin -- luminous fungi -- substrate of luminescent reaction
Аннотация: The luminescent response of the enzymatic system of Armillaria borealis on the cold and hot extracts from cell-free culture liquids of Inonotus obliquus, Pholiota sp. and A. borealis was examined. The greatest influence on the light emission produced by the luminescent system of A. borealis was provided by the temperature at which the probes were prepared for assay. Boiling a culture liquid on water bath for a few minutes promoted a multifold increase in the luminescence. The results of luminescence assay suggest that the substance involved in the bioluminescent reaction in higher fungi is presented in culture liquids and mycelia in two forms. In one form, it is ready to interact with the enzymatic system and in the second form, it becomes accessible for the reaction after heat treatment. The pool of thermoactivated substance was found to be much large than the amount of the ready accessible one. We suggest that predecessors of hispidin, which is fungal luciferin precursor, are responsible for this phenomenon. They are not involved in bioluminescence at their original state and are converted into the substrate under the influence of high temperature. © 2019, © 2019 The Author(s).
