Figure 2.
The pseudo DNA duplex of the Z1-TTT complex structure viewed from (a) front and (b) side view. A pseudo-continuous right-handed duplex DNA is formed by the complementary base pairing between A and C chains and B and D, respectively shown as cartoon representation. The Z1 intercalates through the minor groove side into the 5’-C3pT4 step shown in blue stick and surface.
