Protein attributes

Sequence length	998 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	ATP-dependent serine protease that mediates the selective degradation of mutant and abnormal proteins as well as certain short-lived regulatory proteins. Degrades polypeptides processively By similarity.
Subunit structure	Homohexamer. Organized in a ring with a central cavity By similarity.
Subcellular location	Cell membrane By similarity; Multi-pass membrane protein Potential.
Post-translational modification	This protein undergoes a protein self splicing that involves a post-translational excision of the intervening region (intein) followed by peptide ligation Potential.
Sequence similarities	Belongs to the peptidase S16 family. Archaeal LonB subfamily. Contains 1 DOD-type homing endonuclease domain.
