Location of the CBF3 complex on yeast CEN DNA. (A) Scaled diagram of the linear 914-bp CEN DNA NdeI/AflIII restriction fragment showing the locations (in nanometers, numbered from the left) of CDEI, CDEII, and CDEIII. (B) Scaled diagrams illustrate this DNA molecule containing a CBF3 complex. The region of DNA covered by the CBF3 complex is indicated by a circle and the 23-nm reduction in contour length is indicated by a vertical arrow within the circle. The diameter of the circle shows the width of the complex at half-maximal height. The vertical stripes on each side of the circle indicate the apparent width of the base of the CBF3 complex, which is broadened by an amount comparable to the width of the AFM tip. In diagram B-1 the location of the complex relative to CDEI and CDEIII assumes that the long DNA arm extends to the left of CDEIII. In B-2, it is assumed that the long DNA arm extends to the right of CDEIII. All measurements are in nm. The core and extended complexes are indicated according to refs. 2 and 3.
