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.
Catalytic activity	Hydrolysis of proteins in presence of ATP.
Subunit structure	Homohexamer. Organized in a ring with a central cavity By similarity.
Subcellular location	Cytoplasm.
Induction	By heat shock By similarity.
Sequence similarities	Belongs to the peptidase S16 family. Contains 1 Lon domain.
