EC 3.4.21.53     
Accepted name: endopeptidase La
Reaction: Hydrolysis of proteins in presence of ATP
Other name(s): ATP-dependent serine proteinase; lon proteinase; protease La; proteinase La; ATP-dependent lon proteinase; ATP-dependent protease La; Escherichia coli proteinase La; Escherichia coli serine proteinase La; gene lon protease; gene lon proteins; PIM1 protease; PIM1 proteinase; serine protease La
Comments: Product of the lon gene in Escherichia coli. ATP hydrolysis is linked with peptide bond hydrolysis; vanadate inhibits both reactions. Type example of peptidase family S16. A similar enzyme occurs in animal mitochondria
