Regulation summary diagram for bssS

There have been contradictory reports on the effect of a bssS mutation on biofilm formation. [Beloin04] reported that a bssS mutant is impaired in biofilm formation, while [Domka06] reported that deletion of bssS leads to increased biofilm formation in LB+glucose and MC9C+glucose media and increased motility in LB medium.

A bssS deletion mutant does not have a significant growth defect. Deletion of bssS affects the expression of more than 400 genes significantly. Among the affected pathways are indole transport and AI-2 uptake and processing. A regulatory model has been proposed [Domka06].

Transcription of bssS is induced upon biofilm formation compared to planktonic growth in both exponential and stationary phase [Schembri03, Beloin04, Ren04b]. Induction of expression was found to be dependent on the presence of the F plasmid [Beloin04].

BssS: "regulator of biofilm through signal secretion" [Domka06]
