Owttrim, George W., Magee, Wendy C., Yu, Esther, Chamot, Danuta
The ability to modify RNA secondary structure is crucial for numerous cellular processes. We have characterized two RNA helicase genes, crhB and crhC, which are differentially expressed in the cyanobacterium Anabaena sp. strain PCC 7120. crhC transcription is limited specifically to cold shock...

A LexA-related protein regulates redox-sensitive expression of the cyanobacterial RNA helicase, crhR
Download2006
Colvin, Kimberley R., Owttrim, George W. , Patterson-Fortin, Laura M.
Expression of the cyanobacterial DEAD-box RNA helicase, crhR , is regulated in response to conditions, which elicit reduction of the photosynthetic electron transport chain. A combination of electrophoretic mobility shift assay (EMSA), DNA affinity chromatography and mass spectrometry identified...

Biofouling is a serious problem in the medical, marine, and several other industrial fields as it poses significant health risks and financial losses. Therefore, there is a great need to endow surfaces with antifouling and antimicrobial properties to mitigate biofouling. For long-term biofouling...

Characterization of the Type VI Secretion System in the Bacterial Pathogen Acinetobacter baumannii
DownloadFall 2016
Antibiotic resistant bacteria that cause hospital-acquired infections are a mounting concern for healthcare systems globally. Multidrug resistant (MDR) Acinetobacter baumannii has emerged as a common cause of nosocomial infections, and some isolates are now pandrug resistant. These infections can...

Characterizing the Mesolimbic Dopamine Reward Pathway in a Magel2-null Mouse, a Model of Prader-Willi Syndrome
DownloadFall 2016
Prader-Willi Syndrome (PWS) is a genetic disorder characterized by extreme hyperphagia that can lead to severe obesity. The abnormal motivation to eat in PWS suggests a disruption in the hedonic feeding pathway, which is feeding based on reward as opposed to physiological need. Hedonic feeding is...

Comparative analysis of two phenotypically-similar but genomically-distinct Burkholderia cenocepacia-specific bacteriophages
Download2012
Stothard, Paul, Dennis, Jonathan J., Lynch, Karlene H.
Background Genomic analysis of bacteriophages infecting the Burkholderia cepacia complex (BCC) is an important preliminary step in the development of a phage therapy protocol for these opportunistic pathogens. The objective of this study was to characterize KL1 (vBBceSKL1) and AH2 (vBBceSAH2),...

Conditional, temperature-induced proteolytic regulation of cyanobacterial RNA helicase expression
Download2014
Owttrim, George W., Tarassova, Oxana S., Chamot, Danuta
Conditional proteolysis is a crucial process regulating the abundance of key regulatory proteins associated with the cell cycle, differentiation pathways, or cellular response to abiotic stress in eukaryotic and prokaryotic organisms. We provide evidence that conditional proteolysis is involved...

Cuticular plasticization in the tick, Amblyomma hebraeum (Acari: Ixodidae): possible roles of monoamines and cuticular pH
Download2010
Reynolds, S. E., Flynn, P. C., Kaufman, W. R.
Abstract: The degree of plasticization of the alloscutal cuticle of a 'hard' (ixodid) tick, Amblyomma hebraeum, and a 'soft' (argasid) tick, Ornithodoros moubata, was assessed throughout the blood-feeding period. Cuticle viscosity was calculated from rate of creep of cuticle under constant load...

Cyanobacterial RNA Helicase CrhR Localizes to the Thylakoid Membrane Region and Cosediments with Degradosome and Polysome Complexes in Synechocystis sptrain PCC 6803
Download2016
Fahlman, Richard P., Owttrim, George W. , Rosana, Albert R. R., Whitford, Denise S.
The cyanobacterium Synechocystis sp. strain PCC 6803 encodes a single DEAD box RNA helicase, CrhR, whose expression is tightly autoregulated in response to cold stress. Subcellular localization and proteomic analysis results indicate that CrhR localizes to both the cytoplasmic and thylakoid...
