Purity ~90% (SDS-PAGE). 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. Source: Recombinant protein corresponding to aa1-206 from mycoplasma pneumoniae Lon Protease, fused to His-SUMO-Tag at N-terminal, expressed in E. coli. Molecular Weight: ~39.8kD AA
