Mechanism and color modulation of fungal bioluminescence

Mechanism and color modulation of fungal bioluminescence

Bioluminescent fungi are spread throughout the globe, but details on their mechanism of light emission are still scarce. Usually, the process involves three key components: an oxidizable luciferin substrate, a luciferase enzyme, and a light emitter, typically oxidized luciferin, and called oxyluciferin. We report the structure of fungal oxyluciferin, investigate the mechanism of fungal biolumin...

Spectroscopic studies of the color modulation mechanism of firefly (beetle) bioluminescence with amino-analogs of luciferin and oxyluciferin.

Spectroscopic properties of amino-analogs of luciferin and oxyluciferin were investigated to confirm the color modulation mechanism of firefly (beetle) bioluminescence. Fluorescence solvatochromic character of aminooxyluciferin analogs indicates that the bioluminescence of aminoluciferin is useful for evaluating the polarity of a luciferase active site.

Illuminating Fungal Infections with Bioluminescence

BLI is a powerful biophotonic imaging technology that allows in vivo visualization of temporal and spatial progression of infections in living organisms. BLI relies on the detection of visible light arising from an enzymatic reaction of oxidation known as bioluminescence. Originally, bioluminescence referred to the light emission of living organisms (e.g., bacteria, fungi, fish, insects, algae,...

Circadian Control Sheds Light on Fungal Bioluminescence

Bioluminescence, the creation and emission of light by organisms, affords insight into the lives of organisms doing it. Luminous living things are widespread and access diverse mechanisms to generate and control luminescence [1-5]. Among the least studied bioluminescent organisms are phylogenetically rare fungi-only 71 species, all within the ∼ 9,000 fungi of the temperate and tropical Agarical...
