  Evaluation Summary:

  Acyl-homoserine lactone (AHL) based quorum sensing systems are an important form of intercellular communication in bacteria. These systems, minimally comprised of a synthase and a receptor, often involve different types of AHLs. This paper demonstrates that amino acids in the active site of the synthase and the binding site of the receptor have co-evolved to provide specificity for different signaling molecules, even though the synthase and receptor do not directly interact. This type of information could potentially be used to rationally engineer synthases and receptors with different specificities, as well as predict the specificities of uncharacterized synthases and receptors.

  Evaluation Summary:

  The authors found a mechanosensitive channel gene in T. cruzi, and aimed to characterize its functions. The authors provide conclusive evidence that TcMscS is a mechanosensitive channel. They also show that TcMscS has additional roles outside of mechanosensation, likely playing a role in the infectivity of T. cruzi.
