The fingers domain help with guiding the RNA into the active site. More specifically, the RNA interacts directly with residues 14, 93, 95, 97, 98, 139, 141, and 160. A <scene name='89/891378/Residues_with_rna/2'>Space Fill</scene> diagram better shows these interactions. | The fingers domain help with guiding the RNA into the active site.

A <scene name='89/891378/Residues_with_rna/2'>Space Fill</scene> diagram better shows these interactions. The active site is "encircled" due to interactions between the thumb and fingers domain. In many polymerases, this structure undergoes a tightening conformation change when the substrate is bound. The HCV RdRp undergoes very minimal conformation change between bound and unbound active sites. The RdRp performs efficiently in native conformation. | ||
