Lon protease 1

Gene

lon1

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

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). Has been implicated in preventing sigma(G) activity under non-sporulation conditions.UniRule annotation
