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}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=CAC11154.1; Type=Erroneous initiation; Evidence={ECO:0000305};
