General annotation (Comments)

Function

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. HAMAP-Rule MF_00091

Catalytic activity

S-(5-deoxy-D-ribos-5-yl)-L-homocysteine = L-homocysteine + (4S)-4,5-dihydroxypentan-2,3-dione. HAMAP-Rule MF_00091

Cofactor

Binds 1 iron ion per subunit By similarity. HAMAP-Rule MF_00091

Subunit structure

Homodimer By similarity. HAMAP-Rule MF_00091

Sequence similarities

Belongs to the LuxS family.
