摘　　要：色素蛋白复合体是光合生物进行光合作用维持生命活动最重要的结构基础。目前不产氧光合细菌色素蛋白复合体仍是最具前沿研究领域。本文概述了不产氧光合细菌各种属色素蛋白复合体研究现状,着重对光反应中心色素蛋白复合体(reaction center,RC)和捕光色素蛋白复合体(light-harvesting complex,LH),尤其是新型捕光色素蛋白复合体LH3和LH4的组成、精细结构、蛋白同源性和功能进行了述评,并就研究中存在的问题和发展趋势进行了讨论。Anoxygenic phototrophic bacteria have evolved highly efficient systems-membrane-located pigment-protein complexes which can convert sunlight into chemical energy that they can use and also benefit other organisms. More and more attentions have been paid to pigment-protein complexes of anoxygenic phototrophic bacteria in recent years. We summarized the current opinions in the pigment-protein complexes from anoxygenic phototrophic bacteria, including their chemical compositions, crystal structures and functions, homology of protein sequence. In particular, we depicted the novel light-harvesting complexes namely LH3 and LH4. The problems and prospects about the pigment-protein complexes have also been addressed in this review.
