RT   "Complete sequence of Pyrobaculum islandicum DSM 4184.";
RL   Submitted (DEC-2006) 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 beta chain is a regulatory subunit.
CC       {ECO:0000255|HAMAP-Rule:MF_00310}.
CC   -!- SIMILARITY: Belongs to the ATPase alpha/beta chains family.
CC       {ECO:0000255|HAMAP-Rule:MF_00310}.
