绿藻叶绿体的光取向受蓝光和红光的控制。趋光素A和B的LOV结构域的性质与蓝光介导的光定向的作用光谱和感光体寿命的数据一致。新色素的LOV结构域不与黄素结合，而新色素2的结构域有助于多聚体的形成。新色素光敏结构域与光敏色动蛋白的吸收光谱与红光诱导光定向的作用光谱非常相似。这些结果表明，趋光素和新色素是参与光定向的蓝、红光感受器。(C)2006年欧洲生化学会联合会。爱思唯尔出版，版权所有。
Chloroplast photoorientation in the green alga Mougeotia scalaris is controlled by blue and red light. The properties of the LOV domains of phototropin A and B were consistent with previous data of action spectra and photoreceptor lifetime for blue light-mediated photoorientation. The LOV domains of the neochromes did not bind flavin, while the domains of neochrome 2 contributed to multimer formation. The absorption spectra of the neochrome phytochrome photosensory domain with phytochromobilin were very similar to the action spectra for red light-induced photoorientation. These results indicate that phototropin and neochrome work as the blue and red photoreceptors involved in photoorientation. (c) 2006 Federation of European Biochemical Societies.
