Characterization of the cold stress-induced cyanobacterial DEAD-box protein CrhC as an RNA helicase
Download2000
Owttrim, George W., Yu, Esther
We have shown previously that CrhC is a unique member of the DEAD-box family of RNA helicases whose expression occurs specifically under conditions of cold stress. Here we show that recombinant His-tagged CrhC, purified from Escherichia coli, is an ATP-independent RNA binding protein possessing...

The mechanism of action of cidofovir and (S)-9-(3-hydroxy-2-phosphonomethoxypropyl)adenine against viral polymerases
DownloadFall 2009
The nucleoside phosphonates cidofovir (CDV) and (S)-9-[3-hydroxy-(2-phosphonomethoxy)propyl]adenine [(S)-HPMPA] are analogs of dCMP and dAMP, respectively. Collectively these drugs are effective inhibitors of a wide range of DNA viruses, RNA viruses, and retroviruses. Because they are nucleotide...

A large deletion virus reveals the presence of previously uncharacterized vaccinia virus inhibitors of NF-kB signaling
DownloadFall 2010
The classical Nuclear Factor kappa B (NF-κB) signaling pathway is an important regulator of inflammation and innate immune responses. Poxviruses, including vaccinia virus, encode multiple immune evasion proteins, including a growing number of NF-κB inhibitors. To determine if additional vaccinia...

Mast cells are immune cells important in innate immunity. Besides their role in asthma and allergies, mast cells are critical effector cells against various pathogens. Mast cells are established to be protective against bacterial infections, but little is known about their functions in viral...

The introduction of WNV into North America in 1999 was followed by rapid spread throughout the continent. Today, WNV is an endemic pathogen in the west, with thousands of cases of severe infection reported annually. In addition to traditional vaccine research, there is an urgent need to...

The [1,2]-Stevens Rearrangement of Oxonium Ylides: Synthetic Applications and Mechanistic Studies
DownloadSpring 2016
The Stevens [1,2]-rearrangement of onium ylides has been employed as a valuable synthetic method to construct new C-C bonds. Oxonium ylides are reactive intermediates that undergo facile Stevens rearrangement under mild conditions. In the last several decades, the Stevens rearrangement of oxonium...

Most antivirals target viral proteins and are specific for only one virus, or even one viral genotype. Whereas viral proteins are encoded in the plastic viral genome, virion lipids are not and their rearrangements during fusion of the virion envelope to cellular membranes are conserved among...

Inhibition and enhancement of Respiratory Syncytial Virus replication by nucleoside analogues and bis(indole) compounds
DownloadSpring 2019
Respiratory syncytial virus (RSV) is an Orthopneumovirus that infects the epithelium of the airways. Severe RSV infection of the lower respiratory tract in infants is a leading cause of pediatric hospitalizations. RSV also causes substantial morbidity in immunocompromised and elderly populations....
