Protein attributes

Sequence length	1013 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Produces ATP from ADP in the presence of a proton gradient across the membrane. The archaeal alpha chain is a catalytic subunit. HAMAP MF_00309
Catalytic activity	ATP + H2O + H+(In) = ADP + phosphate + H+(Out). HAMAP MF_00309
Post-translational modification	This protein undergoes a protein self splicing that involves a post-translational excision of the VDE intervening region (intein) followed by peptide ligation Potential. HAMAP MF_00309
Miscellaneous	The intein interrupts the ATP-binding site. HAMAP MF_00309
Sequence similarities	Belongs to the ATPase alpha/beta chains family. Contains 1 DOD-type homing endonuclease domain.
