RT   hyperthermophilic sulfur-dependent archaeum, Thermococcus sp. KI.";
RL   Biochim. Biophys. Acta 1329:12-17(1997).
CC   -!- FUNCTION: Produces ATP from ADP in the presence of a proton gradient
CC       across the membrane. The archaeal beta chain is a regulatory subunit.
CC   -!- SIMILARITY: Belongs to the ATPase alpha/beta chains family.
CC       {ECO:0000305}.
