by two FPH-1 molecules for 35 different oligomeric duplexes. Single basepair mismatches in the FPH-1 binding site were found to cause significant decreases in K(1)K(2) of 18- to 2300-fold. Thermal denaturation experiments provided similar results. Arguments are presented which favor the structure of the (FPH-1)(2):dsDNA minorgroove complex to involve the two FPH-1 molecules in a slightly staggered
