RNA helicases function as molecular motors that rearrange RNA secondary structure, potentially performing roles in any cellular process involving RNA metabolism. Although RNA helicase association with a range of cellular functions is well documented, their importance in response to abiotic stress...
Cyanobacterial biofactories: combining evolved and synthetic genetic regulatory mechanisms to yield carbon-neutral bioproductsDownload
Brand, Logan A., Owttrim, George W.
While cyanobacteria hold the promise of producing useful bioproducts from little more than sunlight and carbon dioxide, their economic feasibility hinges on developing better mechanisms to manipulate gene expression in order to divert photosynthate towards product formation. A recent report...
Cyanobacterial RNA Helicase CrhR Localizes to the Thylakoid Membrane Region and Cosediments with Degradosome and Polysome Complexes in Synechocystis sptrain PCC 6803Download
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...
A LexA-related protein regulates redox-sensitive expression of the cyanobacterial RNA helicase, crhRDownload
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...
