*CLP P subunit
+
CLP is a heterodimer containing an ATP-binding regulatory subunit A '''ClpA''' or Hsp100 in [[Heat Shock Proteins]] and catalytic subunit P '''ClpP'''. The proteolytic complex is composed of <scene name='50/508398/Cv/2'>2 heptameric rings of ClpP</scene> flanked by hexameric rings of ClpA. For full proteolytic activity ClpP must associate with one of two related ATPase subunits: '''ClpA''' and '''ClpX''' or '''ATP-binding Clp protease ATP-binding subunit ClpX'''.
