NS5B with B form DNA from HIV Reverse Transcriptase co-crystal model. DNA was modeled in by alignment of palms domain. A beta hairpin in the thumb domain has been moved to accommodate DNA, the hairpin is modeled into the minor groove, a possible binding site. Catalytic Mg2+ ions are modeled in green, these would be coordinated by the three aspartic acid carboxylates, (D220, D318 and D319).

The template strand is seen entering through a gap in the fingers domain, incoming nucleotide that extends the primer lines up with the NS5B active site and duplex DNA exits the enzyme through the large central hole.
