蛋白质发光（proteinicluminescence） 蛋白质吸收280nm左右的紫外光，可引起激发态并有发光。发光的蛋白质主要是苯丙氨酸（荧光峰位282nm）、酪氨酸（303nm）及色氨酸（348nm）这三种芳香氨基酸。这些氨基酸可用作蛋白质荧光的内在探针。蛋白质的结构对其荧光有很大影响，测量荧光谱可鉴别蛋白质结构。蛋白质也可以发磷光，因而磷光也可用来研究蛋白质构象与动力学。蛋白质磷光主要由色氨酸与酪氨酸贡献。
这种感染不会损伤细胞，但是当病毒复制并感染新的癌细胞时，发光的蛋白质也会增多，从而使肿瘤变得越来越亮。
The infection did not harm the cells, but as the virus replicated and infected new cancer cells, the glowing protein multiplied too. This caused the tumours to grow brighter and brighter.

去年，丘奇的研究团队通过自组装获得了合成核糖体，并产生了荧光素酶，这种蛋白质可以使萤火虫发光。
Though they haven’t published their results yet, last year his team got a synthetic ribosome to self-assemble and produce luciferase, the protein that makes fireflies glow.
