Autoregulation of RNA helicase expression in response to temperature stress in Synechocystis spCC 6803
Download2012
Owttrim, George W., Chamot, Danuta, Rosana, Albert R. R.
RNA helicases are ubiquitous enzymes whose modification of RNA secondary structure is known to regulate RNA function. The pathways controlling RNA helicase expression, however, have not been well characterized. Expression of the cyanobacterial RNA helicase, crhR, is regulated in response to...

The introduction of WNV into North America in 1999 was followed by rapid spread throughout the continent. Today, WNV is an endemic pathogen in the west, with thousands of cases of severe infection reported annually. In addition to traditional vaccine research, there is an urgent need to...

Mixing displays a major role in the growth of photosynthesis microorganisms in active suspensions: it gives access to nutrients, improves the microorganisms’ exposure to light, and homogenizes temperature distribution in photobioreactors (PBRs). Therefore, mixing is an essential factor in the...

Despite their small size and apparent simplicity, viruses are capable of causing mass casualties, political turmoil, and global economic shut down. Due to their minimal genome (~10–12 kb), arboviruses such as Zika (ZIKV), Dengue (DENV), and Mayaro (MAYV) depend on many host molecules for...

RNA helicases function in all aspects of RNA metabolism, regulating a diverse range of cellular processes by rearranging RNA structures and mediating RNA-protein interactions. Prokaryotic RNA helicases have been shown to have roles in RNA degradation, ribosome biogenesis and translation, with...

West Nile virus (WNV) is a neurotropic, blood-borne flavivirus that can cause serious neurological disease in humans and animals. While significant progress has been made in identifying virus-encoded pathogenic determinants, very little is known regarding how these viral proteins interact with...

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...

Proteolysis autoregulates expression of the cyanobacterial DEAD-box RNA helicase CrhR, in response to change in growth temperature
DownloadFall 2013
The DEAD box cyanobacterial RNA helicase redox, CrhR, in Synechocystis sp. PCC 6803 is induced in response to environmental stress conditions causing reduction of the redox status of the photosynthetic electron transport chain, with temperature being one of the major conditions commonly...

Redox and Light Derived Mechanisms of Environmental Perception are Utilized for Regulation of the Cyanobacterial RNA Helicase crhR
DownloadSpring 2020
Cyanobacteria occur worldwide in environments that contain water and sunlight. They are crucial, positive players in carbon, oxygen and nitrogen cycling and function as producers of biosynthetic products such as biofuels. To optimize these processes, understanding mechanisms by which...
