This family includes four different proteins from E. coli alone. One of them, YdgG or TqsA, has been shown to mediate transport of the quorum-sensing signal autoinducer 2 (AI-2). It is not clear if TqsA enhances secretion of AI-2 or inhibits AI-2 upt ...
This family includes four different proteins from E. coli alone. One of them, YdgG or TqsA, has been shown to mediate transport of the quorum-sensing signal autoinducer 2 (AI-2). It is not clear if TqsA enhances secretion of AI-2 or inhibits AI-2 uptake. By altering the intracellular concentration of AI-2, TqsA affects gene expression in biofilms and biofilm formation [1]. TsqA belongs to the AI-2 exporter (AI-2E) superfamily [2].
