| UniProt functional annotation for P31853 | |||
| UniProt code: P31853. |
| Organism: | Spinacia oleracea (Spinach). | |
| Taxonomy: | Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; Caryophyllales; Chenopodiaceae; Chenopodioideae; Anserineae; Spinacia. | |
| Function: | 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). {ECO:0000250}. | |
| Function: | Component of the F(0) channel, it forms part of the peripheral stalk, linking F(1) to F(0). The b'-subunit is a diverged and duplicated form of b found in plants and photosynthetic bacteria (By similarity). {ECO:0000250}. | |
| Subunit: | F-type ATPases have 2 components, F(1) - the catalytic core - and F(0) - the membrane proton channel. F(1) has five subunits: alpha(3), beta(3), gamma(1), delta(1), epsilon(1). F(0) has four main subunits: a(1), b(1), b'(1) and c(10-14). The alpha and beta chains form an alternating ring which encloses part of the gamma chain. F(1) is attached to F(0) by a central stalk formed by the gamma and epsilon chains, while a peripheral stalk is formed by the delta, b and b' chains (By similarity). {ECO:0000250}. | |
| Subcellular location: | Plastid, chloroplast thylakoid membrane; Single- pass membrane protein. | |
| Miscellaneous: | In plastids the F-type ATPase is also known as CF(1)CF(0). | |
| Similarity: | Belongs to the ATPase B chain family. {ECO:0000305}. | |
