Structurally Conserved Amino Acid W501 Is Required for RNA Helicase Activity but Is Not Essential for DNA Helicase Activity of Hepatitis C Virus NS3 Protein
ABSTRACT Hepatitis C virus (HCV) is a positive-strand RNA virus that encodes a helicase required for viral replication. Although HCV does not replicate through a DNA intermediate, HCV helicaseExpand

A 1.35V 4.3GB/s 1Gb LPDDR2 DRAM with controllable repeater and on-the-fly power-cut scheme for low-power and high-speed mobile application
TLDR
We present an on-the-fly power-cut scheme that can be applied to mobile DRAM without any special modes and a global data-line repeater scheme to reduce the data- line delay. Expand

Preparation of 5-Alkenyl- and 5-Dienyl-2-pyrrolidinone Derivatives
Abstract Glutamic acid is readily converted into N-butenyl-2-pyrrolidi-none-5-carboxaldehyde. The novel butenyl protecting group allows the synthesis of this aldehyde which can be olefinated usingExpand

A new lactam protecting group
N-Alkenyl and N-alkoxymethyl lactams are impervious to many reagents and are useful protecting groups for lactams. Conversion to the corresponding 2-ethoxy iminium salt and hydrolysis in neutralExpand

Asymmetric synthesis of (S)-4-aminohex-5-enoic acid: a potent inhibitor of 4-aminobutyrate-2-oxoglutarate aminotransferase
The potent inhibitor of 4-aminobutyrate-2-oxoglutarate aminotransferase (GABA-T), 4-aminohex-5-enoic acid (vinyl GABA), has been synthesized with excellent enantioselectivity in six steps fromExpand
