(A, left) Modeling of complexes of AZT-terminated DNA primer/DNA template/RT (WT) in the crystal structure of the pretranslocation complex (PDB: 1N6Q) indicating structural fitting to Tyr115, (A, right) Van-der-Waals radii of 2′-(α)-hydrogen in (A) was shown. (B, left) Modeling of complexes of 2′-(α)-F-3′-azido-Ur-terminated DNA primer/DNA template/RT (WT) in the structure of the pretranslocation complex indicates steric clashes to Tyr115, (B, right) Van-der-Waals radii of 2′-(α)-fluorine was shown. (C, left) Modeling of complexes of AZT-terminated DNA primer/DNA template/RT (WT) in the crystal structure of the post-translocation complex indicates structural fitting to Asp185. (C, right) Van-der-Waals radii of 2′-(α)-hydrogen was shown. (D, left) Modeling of complexes of 2′-(α)-F-3′-azido-Ur-terminated DNA primer/DNA template/RT (WT) in the structure of the post-translocation complex indicates steric interaction with Aps185, (D, right) Van-der-Waals radii of 2′-(α)-fluorine was shown. 2′ C–F bond length in C and D was adjusted to 1.399 Å.
