The enzyme that turns on the light for a glow-in-the-dark mushroom seems “promiscuous,” researchers say. But in a good way.
Researchers from Brazil, Russia and Japan have worked out new details of how two Neonothopanus fungi shine softly green at night. The team had earlier figured out that the basic starting material for bioluminescence in these fungi is a compound called hispidin, found in some other fungi as well as plants such as horsetails. Those plants don’t spontaneously give off light, but in the two Neonothopanusmushroom species studied, an enzyme rejiggers a form of hispidin into a compound that glows.
