Progress on pigment-protein complexes from anoxygenic phototrophic bacteria—A review

Abstract:

Abstract: 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.
