Single-molecule kinetics reveal microscopic mechanism by which High-Mobility Group B proteins alter DNA flexibility.

abstract：:We investigated the effects of the antiviral agent distamycin A and of a distamycin derivative (FCE 24517) which possesses antineoplastic activity on the binding of some regulatory proteins to DNA. Both compounds inhibited the binding to DNA of the ubiquitous octamer binding factor OTF 1 and of the erythroid specific ...
