紫细菌光合机构及光合作用基因的表达调控

Photosynthetic Apparatus and Regulation of Photosynthesisgene Expression in Purple Bacteria

摘要:

紫细菌是研究细菌光合作用的重要生物。介绍了紫细菌光合机构捕光色素蛋白复合体Ⅰ(light-harvesting I)、捕光色素蛋白复合体Ⅱ(light-harvesting II)和光化学反应中心(reaction center)的结构, 并探讨了其光合作用基因的转录调控机制, 重点阐述了PpsR/AppA系统对紫细菌光合作用基因的转录调控。

Abstract:

Purple bacteria are extensively used in bacterial photosynthesis research. This review describes the structure of light-harvesting I, light-harvesting II and reaction center of photosynthetic apparatus of purple bacteria and discusses the regulation mechanisms?of photosynthesis (PS) gene transcription, with an emphasis laid on the transcriptional regulation of PS gene by PpsR/AppA system.
