The <scene name='89/891378/Residues_stable_rna/1'>active site</scene> 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. Internal cavities adjacent to the thumb domain are found between structural motifs C and E. This <scene name='89/891378/C_and_e_gap/2'>cavity</scene> is heavily preserved throughout all NS5B models. | ||
