Protein

S-ribosylhomocysteine lyase

Gene
luxS, ASA_0697
Organism
Aeromonas salmonicida (strain A449)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

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) By similarity.UniRule annotation

Catalytic activityi

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

Cofactori

Binds 1 iron ion per subunit By similarity.UniRule annotation
