RT   "Complete sequence of chromosome of Methanococcus maripaludis C5.";
RL   Submitted (MAR-2007) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Produces ATP from ADP in the presence of a proton gradient
CC       across the membrane. The archaeal alpha chain is a catalytic subunit.
CC       {ECO:0000255|HAMAP-Rule:MF_00309}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + 4 H(+)(in) + H2O = ADP + 5 H(+)(out) + phosphate;
CC         Xref=Rhea:RHEA:57720, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=7.1.2.2;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00309};
CC   -!- SIMILARITY: Belongs to the ATPase alpha/beta chains family.
