Fungal bioluminescence is widely distributed in the terrestrial environment. At a specific stage of growth, luminescent fungi shine green light at the fruiting body or mycelium. From the viewpoint of chemistry, fungal bioluminescence involves an in vivo cycle of caffeic acid. The complete cycle is composed of three stages: biosynthesis of luciferin from caffeic acid, luminescence process from luciferin to oxidized luciferin, and regeneration of caffeic acid from oxidized luciferin. Experimental studies roughly proposed this cycle but not the detailed reaction process and mechanism. Our previous theoretical study clearly described the mechanism of the middle stage. The present article attempts to describe the reaction processes and mechanisms of the other two stages by theoretical calculations. A complete theoretical study on the chemistry in the entire process of fungal bioluminescence is helpful to deeply understand fungal bioluminescence.
真菌生物发光在陆地环境中广泛分布。在生长的特定阶段，发光真菌在子实体或菌丝体处发出绿光。从化学角度来看，真菌生物发光涉及咖啡酸的体内循环。完整的循环由三个阶段组成：从咖啡酸生物合成荧光素、荧光素到氧化荧光素的发光过程以及从氧化荧光素再生咖啡酸。实验研究大致提出了这个循环，但没有详细的反应过程和机制。我们之前的理论研究清楚地描述了中间阶段的机制。本文试图通过理论计算描述其他两个阶段的反应过程和机制。对真菌生物发光全过程的化学进行完整的理论研究有助于深入理解真菌生物发光。
