 on the intermolecular triplex (dT)00.(dA)00.(dT)00 has been described \[000\]. Binding of wild-type p00 on plasmid DNA containing triplex-forming sequence demonstrated that p00 prefers a superhelical form of plasmid with triplex extrusion. The use of antibodies to the p00 N- and C-terminal domains showed that the C-terminus of p00 probably plays a key role in triplex TAT binding \[000\].  T
