Definition
The cytochrome b 6 f complex is one of three hetero-oligomeric integral membrane protein complexes in the electron transport chain of oxygenic photosynthesis that contribute to the trans-membrane proton electrochemical potential gradient, \(\Delta{{\mu}^\sim}_{\text H}{^+}\).
Basic Characteristics
Function
Discharge of the \(\Delta{{\mu}\!\!\!^\sim}_{\text H}{^+}\) through the ATP synthase is responsible for adenosine triphosphate (ATP) production. The other two protein complexes in the photosynthetic electron transport chain are the photosystem II (PSII) and photosystem I (PSI) reaction centers. The b 6 f complex functions electrochemically in the center of the linear electron transport chain from H2O to NADP+ in thylakoid or microbial membranes that support oxygenic photosynthesis. b 6 f accepts electrons and protons from PSII via lipophilic plastoquinol, and donates electrons to PSI through the soluble plastocyanin or cytochrome c 6, while...
