Three CF1 and three CF0 subunits of the chloroplast H(+)-ATP synthase are encoded on the chloroplast genome. The chloroplast atp genes are organized as two operons in plants but not in the green alga, Chlamydomonas reinhardtii. The atpBE or β operon shows a relatively simple organisation and transcription pattern, while the atpIHFA or α operon is transcribed into a large variety of mRNAs. The atp genes are related to those of cyanobacteria and, more distantly, to those of non-photosynthetic bacteria such as E. coli, suggesting a common origin of most F1F0 ATP synthase subunits. Both the chloroplast and cyanobacterial ATP synthases have four F0 subunits, not three as in the E. coli complex. The proton pore of the CF0 is proposed to be formed by the interaction of subunits III and IV.
叶绿体 H(+) - ATP 合酶的三个 CF1 和三个 CF0 亚基由叶绿体基因组编码。叶绿体 atp 基因在植物中组织为两个操纵子，但在绿藻衣藻中则不是。atpBE 或β操纵子显示出相对简单的组织和转录模式，而 atpIHFA 或α操纵子转录成多种 mRNA。atp 基因与蓝细菌的基因有关，并且与非光合细菌如大肠杆菌的基因更远，这表明大多数 F1F0 ATP 合酶亚基具有共同的起源。叶绿体和蓝细菌的 ATP 合酶都有四个 F0 亚基，而不是大肠杆菌复合物中的三个。CF0 的质子孔被提议由亚基 III 和 IV 的相互作用形成。
