Protein

S-ribosylhomocysteine lyase

Gene

luxS

Organism
Borrelia burgdorferi (strain ATCC 35210 / B31 / CIP 102532 / DSM 4680)
Status
Reviewed - Annotation score: 2 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).By similarity

Catalytic activityi

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

Cofactori

Binds 1 iron ion per subunit.By similarity
