The Sinorhizobium meliloti chemoreceptor McpU mediates positive and negative chemotaxis responses to dipeptides and competes with periplasmic solute-binding proteins for ligand binding [PDF]

mBio
Many bacteria can utilize extracellular amino acids and peptides as nitrogen sources, metabolic energy, or as an indicator of the environment. Sinorhizobium meliloti, an endosymbiont of alfalfa, is attracted to host-exuded amino acids sensed by the ...
