OX NCBI_TaxID=89652; RN [1] RP NUCLEOTIDE SEQUENCE [GENOMIC DNA]. RX AGRICOLA=IND23320510; RA Stefanovic S., Krueger L., Olmstead R.G.; RT "Monophyly of the Convolvulaceae and circumscription of their major RT lineages based on DNA sequences of multiple chloroplast loci."; RL Am. J. Bot. 89:1510-1522(2002). CC -!- FUNCTION: Produces ATP from ADP in the presence of a proton CC gradient across the membrane. The catalytic sites are hosted CC primarily by the beta subunits (By similarity). CC -!- CATALYTIC ACTIVITY: ATP + H(2)O + H(+)(In) = ADP + phosphate + CC H(+)(Out). CC -!- SUBUNIT: F-type ATPases have 2 components, CF(1) - the catalytic CC core - and CF(0) - the membrane proton channel. CF(1) has five CC subunits: alpha(3), beta(3), gamma(1), delta(1), epsilon(1). CF(0) CC has four main subunits: a(1), b(1), b'(1) and c(9-12) (By CC similarity). CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane; CC Peripheral membrane protein (By similarity). CC -!- SIMILARITY: Belongs to the ATPase alpha/beta chains family.
