Organism

Methanopyrus kandleri (strain AV19 / DSM 6324 / JCM 9639 / NBRC 100938) [Reference proteome] [HAMAP]

Taxonomic identifier

190192 [NCBI]

Taxonomic lineage

cellular organisms › Archaea › Euryarchaeota › Methanopyri › Methanopyrales › Methanopyraceae › Methanopyrus › Methanopyrus kandleri

Protein attributes

Sequence length	990 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 beta chain is a regulatory subunit. HAMAP-Rule MF_00310
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-Rule MF_00310
Sequence similarities	Belongs to the ATPase alpha/beta chains family. Contains 1 DOD-type homing endonuclease domain.
