General annotation (Comments)

Function

Degrades short-lived regulatory and abnormal proteins in the presence of ATP. Hydrolyzes two ATP for each peptide bond cleaved in the protein substrate By similarity. In R.meliloti it is important for controlling the turnover of a constitutively expressed protein(s) that, when unregulated, disrupts normal nodule formation and normal growth.

Catalytic activity

Hydrolysis of proteins in presence of ATP.

Subunit structure

Homotetramer By similarity.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the peptidase S16 family.

Contains 1 Lon domain.
