This domain is found at the C-terminal end of NS3 helicase (Non- structural protein 3-helicase, NS3-Hel) found in Flavivirus such as Zika virus (ZIKV) and Dengue virus type 1 (DENV-1). This protein binds RNA and unwinds dsRNA in the 3' to 5' direction. It consists of three domains. This entry represent the final domain, which is mostly alpha-helical [1,2]. A highly conserved R residue located in this domain was proven essential for the enzymatic activities of the protein [3].	Domain

A, B, C, D	PF00271	Helicase conserved C-terminal domain (Helicase_C)	Helicase conserved C-terminal domain	The Prosite family is restricted to DEAD/H helicases, whereas this domain family is found in a wide variety of helicases and helicase related proteins. It may be that this is not an autonomously folding unit, but an integral part of the helicase.	Domain
