CC   -!- FUNCTION: Involved in the synthesis of autoinducer 2 (AI-2) which is
CC       secreted by bacteria and is used to communicate both the cell density
CC       and the metabolic potential of the environment. The regulation of gene
CC       expression in response to changes in cell density is called quorum
CC       sensing. Catalyzes the transformation of S-ribosylhomocysteine (RHC) to
CC       homocysteine (HC) and 4,5-dihydroxy-2,3-pentadione (DPD).
CC       {ECO:0000255|HAMAP-Rule:MF_00091}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=S-(5-deoxy-D-ribos-5-yl)-L-homocysteine = (S)-4,5-
CC         dihydroxypentane-2,3-dione + L-homocysteine; Xref=Rhea:RHEA:17753,
CC         ChEBI:CHEBI:29484, ChEBI:CHEBI:58195, ChEBI:CHEBI:58199; EC=4.4.1.21;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00091};
CC   -!- COFACTOR:
CC       Name=Fe cation; Xref=ChEBI:CHEBI:24875;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00091};
CC       Note=Binds 1 Fe cation per subunit. {ECO:0000255|HAMAP-Rule:MF_00091};
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00091}.
CC   -!- SIMILARITY: Belongs to the LuxS family. {ECO:0000255|HAMAP-
CC       Rule:MF_00091}.
