General annotation (Comments)

Function

Degrades short-lived regulatory and abnormal proteins in presence of ATP. Hydrolyzes two ATPs for each peptide bond cleaved in the protein substrate. Required for wild-type virulence during the initial stages of infection in the mouse model, but not essential for the establishment and maintenance of chronic infection in this host. Ref.1

Catalytic activity

Hydrolysis of proteins in presence of ATP.

Subunit structure

Homotetramer By similarity.

Subcellular location

Cytoplasm By similarity.

Induction

By stress conditions (acid shock, heat shock, ethanol and puromycin). Ref.1

Sequence similarities

Belongs to the peptidase S16 family.

Contains 1 Lon domain.
