Function

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.

Catalytic activity

  • Hydrolysis of proteins in presence of ATP.
    EC:3.4.21.53 (UniProtKB | ENZYME | Rhea)
