Schematic of inactivation and complementation of luxS. [PDF]

, 2016
(A) Inactivation of luxS by using an ermFermAM cassette. The sequences that flanked the 5′- and 3′- ends of luxS (Coch_1216) were amplified with primers Capno1 and 2, and primers Capno3 and 4, respectively. The ermFermAM cassette was inserted between the

Overexpression of luxS Cannot Increase Autoinducer-2 Production, Only Affect the Growth and Biofilm Formation in Streptococcus suis

The Scientific World Journal, 2013
LuxS/AI-2 quorum sensing (QS) system involves the production of cell signaling molecules via luxS-based autoinducer-2 (AI-2). LuxS has been reported to plays critical roles in regulating various behaviors of bacteria.

Let LuxS speak up in AI-2 signaling [PDF]

, 2006
Quorum sensing is a process of bacterial cell-cell communication that uses small diffusible molecules to coordinate diverse behaviors in response to population density.

Two Lysine Sites That Can Be Malonylated Are Important for LuxS Regulatory Roles in Bacillus velezensis

Microorganisms, 2021
S-ribosylhomocysteine lyase (LuxS) has been shown to regulate bacterial multicellular behaviors, typically biofilm formation. However, the mechanisms for the regulation are still mysterious.

The small regulatory RNA molecule MicA is involved in Salmonella enterica serovar Typhimurium biofilm formation

BMC Microbiology, 2010
Background LuxS is the synthase enzyme of the quorum sensing signal AI-2. In Salmonella Typhimurium, it was previously shown that a luxS deletion mutant is impaired in biofilm formation.
