VATA

Protein name

RecName: Full=V-type ATP synthase alpha chain; EC=3.6.3.14; AltName: Full=V-ATPase subunit A;

Gene name

atpA

FUNCTION: Produces ATP from ADP in the presence of a proton gradient across the membrane. The archaeal alpha chain is a catalytic subunit (By similarity).

FUNCTION: Produces ATP from ADP in the presence of a proton gradient across the membrane. The V-type alpha chain is a catalytic subunit (By similarity).

CATALYTIC ACTIVITY: ATP + H(2)O + H(+)(In) = ADP + phosphate + H(+)(Out).

SIMILARITY: Belongs to the ATPase alpha/beta chains family.
