Cyanobacterial biofactories: combining evolved and synthetic genetic regulatory mechanisms to yield carbon-neutral bioproducts
Download2017-01-01
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...

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...

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...
