This polyprotein is cleaved by viral and cellular proteases to produce mature viral proteins. NS5 is the largest mature viral protein and contains a N-terminal methyltransferase (MTase) domain separated by a short linker from the C-terminal RNA-directed RNA polymerase domain (RdRp) that adopts a characteristic right-handed fingers-palm-thumb fold and possesses a number of short regions and motifs homologous to other RNA-directed RNA polymerases [2,3]. This entry represents the thumb domain of NS5 RdRp. NS5 binds to a the stem loop A (SLA) at the 5' extremity of Flavivirus genome and regulates translation of the viral genome [3].

This entry covers the fingers and palm domains of RNA-directed RNA polymerase (RdRp) from Flavivirus NS5. NS5 binds to a the stem loop A (SLA) at the 5' extremity of Flavivirus genome and regulates translation of the viral genome [5,6].
