RT "Draft genome of Methanospirillum lacunae Ki8-1.";
RL Submitted (MAY-2018) 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:0000256|ARBA:ARBA00003103, ECO:0000256|HAMAP-Rule:MF_00310}.
CC -!- SIMILARITY: Belongs to the ATPase alpha/beta chains family.
CC {ECO:0000256|ARBA:ARBA00008936, ECO:0000256|HAMAP-Rule:MF_00310}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:PWR73211.1}.
