An Overview of the Function, Composition and Structure of the Chloroplast ATP Synthase

  • Richard E. McCarty
Part of the Advances in Photosynthesis and Respiration book series (AIPH, volume 4)


A concise overview of the chloroplast ATP synthase is presented, with an emphasis on its functions, regulation, composition, and structure from fluorescence energy transfer mapping. The ATP synthase may be separated into two parts: coupling factor 1 (CF1) and CF0•CF1 is a large hydrophilic protein that contains the catalytic sites of the synthase. The functions of its five different polypeptides are briefly discussed. CF0 binds CF1 and functions to conduct protons across the thylakoid membrane. Because CF0 will not be considered in detail in subsequent chapters, the composition of CFα and some of its interactions with CF1 are discussed. Insights into the structure and function of CF1 as well as into subunit interactions, gleaned by structural mapping by fluorescence resonance energy transfer, are presented.
