The results show that the G2,G11 and G15 iminos outside both the TGT loop and the two TT loops exchange faster,and in comparison the G6,G5 and G14 iminos have lower exchange rates because of the protection from the TGT loop and the TT loops.

 
  • 我们测定了在K+存在时凝血酶适体DNA中亚氨基质子的交换速率,发现位于TGTloop环和TT loop环内的亚氨基质子G6、G5和G14由于受TGT loop环和TT loop环的保护有比较小的交换速率,而位于环之外的亚氨基质子G2、G11和G15有较大的交换速率;
