Protein
Lon protease
Gene
lon, RF_0692
Organism
Rickettsia felis (strain ATCC VR-1525 / URRWXCal2) (Rickettsia azadi)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

Hydrolysis of proteins in presence of ATP.UniRule annotation
