Xanthophylls are coloured isoprenoid metabolites synthesized in many organisms with a variety of functions from the attraction of animals for impollination to absorption of light energy for photosynthesis to photoprotection against photooxidative stress. The finding by Proctor and co-workers makes a new addition to the last type of functions by showing that zeaxanthin is instrumental in coordinating chlorophyll biosynthesis with the insertion of pigment-binding proteins into the photosynthetic membrane by glueing the protein components catalyzing these functions into a supercomplex and regulating its activity.

叶黄素玉米黄质的新功能：将叶绿素生物合成粘合到类囊体蛋白组装体上

叶黄素是在许多生物体中合成的有色类异戊二烯代谢物，具有多种功能，从吸引动物起泡，吸收光能以进行光合作用到光防护抗光氧化应激。Proctor及其同事的发现通过显示玉米黄质有助于协调叶绿素的生物合成，并通过将催化这些功能的蛋白质成分胶粘到光合作用膜中，从而将色素结合蛋白插入光合膜中，为这一功能提供了新的补充。超复杂并调节其活性。
