Iso-PDF Distribution of PPi and primer RNA strands (A,B) Iso-PDF for bases from the first three primer nucleotides, K593, and PPi for RMP (A) and AMP (B) at position i + 3. (C) Close-up view of iso-PDF for PPi (RMP structure: solid; and AMP structure: transparent). (D) The i + 3 RMP complex structure for showing K593, PPi, and 4 nucleotides of the primer strand. (E) Corresponding i + 3 AMP complex structure. (F) Superposition of the two complexes.
