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...

Fall 2017
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...

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...

Treatment of Antiviral Drugs in Wastewater Using Advanced Oxidation Processes - Ozonation of Oseltamivir Phosphate
DownloadFall 2021
While wastewater treatment facilities are designed to remove contaminants from water before it returns to the environment, unfortunately, not all of these facilities are effective in the removal of micropollutants (MPs). Antiviral drugs are a class of MPs that have become an area of concern due...

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...

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....
