Paper of the month: November 2013

• Cyclic di-AMP is an essential second messenger in B. subtilis and other Gram-positive bacteria. This molecule has been discovered only in 2008, and a lot of work has recently been devoted to the investigation of its function. This month, Nelson et al. from the lab of Ronald Breaker discovered that c-di-AMP binds to the ydaO riboswitch. This is extremely interesting since the molecule does also bind the KtrA potassium transporter. The ktrA-ktrB operon is also controlled by a ydaO riboswitch. Thus c-di-AMP is the first signalling nucleotide that controls a biological process by binding both a protein and the encoding mRNA.
