Photoactive Yellow Protein (PYP) is a small cytosolic photoreceptor that is thought to be involved in the negative phototaxis of the bacterium Ectothiorhodospira halophilia. Its small size and the fact that it is not a membrane protein make it an ideal experimental system for establishing a structural paradigm for photon - protein interactions. In pursuit of this general goal, our lab is also involved in a study of PYP that uses time-resolved Laue diffraction experiments to study structural intermediates its photocycle.

光活性黄色蛋白 (PYP) 是一种小型胞浆蛋白 被认为与负片有关的光感受器 嗜盐外硫红螺菌的趋光性。 它很小 大小以及它不是膜蛋白的事实使其成为理想的 建立光子结构范式的实验系统 - 蛋白质相互作用。 为了实现这一总体目标，我们的实验室 还参与了一项使用时间分辨劳厄的 PYP 研究 衍射实验研究结构中间体其 光循环。
