Protein existenceInferred 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. Required for cellular homeostasis and for survival from DNA damage and developmental changes induced by stress. Degrades polypeptides processively to yield small peptide fragments that are 5 to 10 amino acids long. Binds to DNA in a double-stranded, site-specific manner By similarity. HAMAP-Rule MF_01973

Catalytic activity

Hydrolysis of proteins in presence of ATP. HAMAP-Rule MF_01973

Subunit structure

Homohexamer. Organized in a ring with a central cavity By similarity.

Subcellular location

Cytoplasm By similarity.

Induction

By heat shock By similarity.

Sequence similarities

Belongs to the peptidase S16 family.

Contains 1 Lon domain.
