Abstract
The influence of sixteen base triplet changes at a single position within a pur·pur·pyr triple helix was examined by affinity cleaving. For the 15 base pair target site studied here, G·GC, A·AT and T·AT triplets stabilize a triple helix to a greater extent than the other 13 natural triplets (pH = 7.4, 25°C). Weaker interactions were detected for the C·AT, A·GC and T·CG triplets. The absence of specific, highly stabilizing interactions between third strand bases and the CG or TA base pairs demonstrates a current sequence limitation to formation of this structure. Models for the two dimensional base triplet interactions for all possible 16 natural triplets are presented.
