UniProtKB - Q72YS4 (LUXS_BACC1)
Protein
S-ribosylhomocysteine lyase
Gene
luxS
Organism
Bacillus cereus (strain ATCC 10987 / NRS 248)
Status
Functioni
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).UniRule annotation
