[[http://www.uniprot.org/uniprot/ATPH_WHEAT ATPH_WHEAT]] F(1)F(0) ATP synthase produces ATP from ADP in the presence of a proton or sodium gradient. F-type ATPases consist of two structural domains, F(1) containing the extramembraneous catalytic core and F(0) containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation (By similarity). Key component of the F(0) channel; it plays a direct role in translocation across the membrane. A homomeric c-ring of between 10-14 subunits forms the central stalk rotor element with the F(1) delta and epsilon subunits (By similarity). | [[http://www.uniprot.org/uniprot/ATPH_WHEAT ATPH_WHEAT]] F(1)F(0) ATP synthase produces ATP from ADP in the presence of a proton or sodium gradient.

== Publication Abstract from PubMed == | |||
In eukaryotic- and prokaryotic cells F-ATP synthases provide energy through the synthesis of adenosine triphosphate (ATP). The chloroplast F-ATP synthase (CF1FO-ATP synthase) of plants is integrated into the thylakoid membrane via its FO-domain subunits a, b, b' and c. Subunit c with a stoichiometry of 14 and subunit a form the gate for H+-pumping, enabling the coupling of electrochemical energy with ATP synthesis in the F1 sector. Here we report the crystallization and structure determination of the c14-ring of subunit c of the CF1FO-ATP synthase from spinach chloroplasts. The crystals belonged to space group C2, with unit-cell parameters a = 144.420, b = 99.295, c = 123.51 A, and beta = 104.34 masculine and diffracted to 4.5 A resolution. Each c-ring contains fourteen monomers in the asymmetric unit. The length of the c-ring is 60.32 A, with an outer ring diameter 52.30 A, and an inner ring width of 40 A. | |||
