Protein attributes

Sequence length	157 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

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. SAAS SAAS003815
Catalytic activity	S-(5-deoxy-D-ribos-5-yl)-L-homocysteine = L-homocysteine + (4S)-4,5-dihydroxypentan-2,3-dione. SAAS SAAS003815
Cofactor	Binds 1 iron ion per subunit By similarity. SAAS SAAS003815
Subunit structure	Homodimer By similarity. SAAS SAAS003815
