Due to minute size and limited sequence complexity small proteins can be challenging to identify, but are emerging as important regulators of diverse processes in bacteria. In this issue of the Journal of Bacteriology Kraus and co-workers report comprehensive analysis of a fascinating sub-family of arginine-rich, small proteins in Agrobacterium tumefaciens, conserved among Alphaproteobacteria. Their findings reveal that these small proteins are under complex regulation and have a disproportionately large impact on metabolism and behavior.
