1,8-Cineole inhibits biofilm formation and bacterial pathogenicity by suppressing luxS gene expression in Escherichia coli

Frontiers in Pharmacology, 2022
In recent years, with frequent reports of multi-drug resistant strains, bacteria antibiotic resistance has become an increasingly serious health problem worldwide.

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.

Transcriptional and post-transcriptional regulation of the Escherichia coli luxS mRNA; involvement of the sRNA MicA.

PLoS ONE, 2010
BackgroundThe small RNA (sRNA) MicA has been shown to post-transcriptionally regulate translation of the outer membrane protein A (OmpA) in Escherichia coli.

The Impairment of Methyl Metabolism From luxS Mutation of Streptococcus mutans

Frontiers in Microbiology, 2018
The luxS gene is present in a wide range of bacteria and is involved in many cellular processes. LuxS mutation can cause autoinducer(AI)-2 deficiency and methyl metabolism disorder. The objective of this study was to demonstrate that, in addition to AI-2-

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.

Schematic of inactivation and complementation of luxS.

, 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
