LuxS Protein, E. coli, Recombinant (His)

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) . LuxS Protein, E. coli, Recombinant (His) is expressed in E. coli expression system with N-6xHis tag. The predicted molecular weight is 23.3 kDa and the accession number is P45578.
