Stability of complexes of his6Tus with the variant Ter DNAs. The data show the decreasing amounts of his6Tus in the complex with dsDNA (Tuscomplex) as a percentage of the total amount of Tus (Tustotal), as a function of NH4OAc concentration. (diamonds) his6Tus–TerB, (triangles) his6Tus–posn5Ter, (squares) his6Tus–TerH, (multiplication symbols) his6Tus–posn7TerB, (plus signs) his6Tus–posn10TerB.
