Small molecules that bind in the minor groove of DNA are in clinical use as antibiotics and antitumor drugs. Two members of this class of molecules, netropsin and chromomycin, are shown here to displace DNA from the nucleosome and promote transfer of the histone octamer to an acceptor protein. The effects of these groove-binding molecules are exploited to address an outstanding problem in the mechanism of the RSC chromatin remodeling complex. RSC and other remodeling complexes are DNA translocases, acting near the center of the nucleosomal DNA, but translocation is apparently impossible because DNA cannot slide across the histone surface in the nucleosome. Netropsin and chromomycin promote the release of DNA from the histone surface, enhance the formation of a RSC-nucleosome complex, and synergize with RSC in chromatin remodeling. These findings are in keeping with an involvement of bulge translocation in chromatin remodeling.
