Protein

S-ribosylhomocysteine lyase

Gene

luxS

Organism
Staphylococcus aureus (strain N315)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Experimental evidence at protein leveli

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

Catalytic activityi

S-(5-deoxy-D-ribos-5-yl)-L-homocysteine = L-homocysteine + (4S)-4,5-dihydroxypentan-2,3-dione.UniRule annotation
