Protein
AI-2 transport protein TqsA
Organism
Escherichia coli (strain K12)
Function
Controls the transport of the quorum-sensing signal AI-2 either by enhancing its secretion or inhibiting its uptake and consequently represses biofilm formation and motility and affects the global gene expression in biofilms.
Similarity
Belongs to the autoinducer-2 exporter (AI-2E) (TC 2.A.86) family.
