Riboswitching on RNA virus replication.
Positive-strand RNA viruses direct different virus-specific processes during their infection of host cells. Fundamental events such as viral RNA genome replication are controlled by viral regulatory RNA elements (REs). Here, we have investigated the possibility of specifically modulating the action of a viral RE using RNA aptamer technology. Through rational design, a tombusvirus RE, which has ...
متن کاملIdentification of RNA aptamers with riboswitching properties.
During the past years customized gene network design has become of tremendous interest among various disciplines in life science. The identification of artificial genetic elements sensitive to internal or external stimuli constitutes the foundation for the design and realization of conditional gene expression systems. Typically, strategies involving selection or screening steps are employed alo...
متن کاملCorrection: Stimulated Bacterial Growth under Elevated pCO2: Results from an Off-Shore Mesocosm Study
Marine bacteria are the main consumers of freshly produced organic matter. Many enzymatic processes involved in the bacterial digestion of organic compounds were shown to be pH sensitive in previous studies. Due to the continuous rise in atmospheric CO2 concentration, seawater pH is presently decreasing at a rate unprecedented during the last 300 million years but the consequences for microbial...
متن کاملBacterial Shape: Growing off this Mortal Coil
Members of the actin-like MreB family of proteins localize as a helical filament in bacteria and are important for determining cylindrical cell shape. Recent results show that new cell wall biosynthesis occurs along a helical track dependent on one of these actin homologs, providing new insights into bacterial cell growth, division and shape.
