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...

Cyanobacterial RNA Helicase CrhR Localizes to the Thylakoid Membrane Region and Cosediments with Degradosome and Polysome Complexes in Synechocystis sptrain PCC 6803

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...

Whitford, Denise S., Owttrim, George W.
Expression of the stress-regulated RNA helicase of Synechocystis sp. PCC 6803, CrhR, is altered by three known stresses, temperature, light and salt concentration. Here we show that altering the source of fixed nitrogen, either urea, ammonia, nitrate or lack of fixed nitrogen, also results in...

RNA structural rearrangement via unwinding and annealing by the cyanobacterial RNA helicase, CrhR
Download2005
Owttrim, George W., Chamot, Danuta, Kujat-Choy, Sonya L., Colvin, Kimberley R.
Rearrangement of RNA secondary structure is crucial for numerous biological processes. RNA helicases participate in these rearrangements through the unwinding of duplex RNA. We report here that the redox-regulated cyanobacterial RNA helicase, CrhR, is a bona fide RNA helicase possessing both...
