Abstract excerpt
The flavivirus genome RNA terminates with a conserved 3' stem loop (SL) structure that was shown to be essential for virus replication. A stretch of conserved nts is located in the top loop (TL) of this structure. Mutation of the TL nts (5' ACAGUGC 3') in a WNV infectious clone indicated that 3 of the 7 TL nts (5' ACAGUGC 3') are critical for virus replication. Mutation of 3 of the other nts reduced the...
