靶點詳情

  • 功能：
    Involved in the synthesis of autoinducer 2 (AI-2) which is secreted by bacteria and is used to communicate both the cell density and the metabolic potential of the environment. The regulation of gene expression in response to changes in cell density is called quorum sensing. Catalyzes the transformation of S-ribosylhomocysteine (RHC) to homocysteine (HC) and 4,5-dihydroxy-2,3-pentadione (DPD).

    1. study demonstrated that luxS affects the expression of flagella and Stx2e toxin, 2 important STEC virulence factors PMID: 24848979
    2. LuxS contributes to virulence in avian pathogenic Escherichia coli O78:K80:H9. PMID: 23958403
    3. Proteomic profiling of luxS mutants showed only a few proteins were differentially expressed and those that were altered suggested a metabolic rather than communication role for the E. coli luxS gene product. PMID: 23651217
    4. Deletion of the luxS gene reduced the bacterial virulence by 31.5-fold in ducklings. PMID: 23046700
    5. Polyphosphate degradation in stationary phase triggers biofilm formation via LuxS quorum sensing system in Escherichia coli. PMID: 23226268
    6. Pfs and LuxS synthesize AI-2 in vitro from S-ribosylhomocysteine. PMID: 23236852
    7. luxS deletion significantly increases swimming motility and flagella synthesis in Escherichia coli K12. PMID: 20875395
    8. These data are consistent with the function of LuxS as an important metabolic enzyme but appear not to support the role of AI-2 as a true signal molecule for E. coli W3110 under the investigated conditions. PMID: 16321939
    9. The active form of LuxS contains a metal-bound water and a thiolate ion at Cys-83, consistent with the proposed roles of the metal ion (Lewis acid) and Cys-83 (general acid/base) during catalysis. PMID: 17014073
