Comments [?]

FUNCTION	Involved in the degradation of phospho-AI-2, thereby terminating induction of the lsr operon and closing the AI-2 signaling cycle. Catalyzes the conversion of (4S)-4-hydroxy-5- phosphonooxypentane-2,3-dione (P-DPD) to 3-hydroxy-5- phosphonooxypentane-2,4-dione (P-HPD).
CATALYTIC ACTIVITY	Reaction=(2S)-2-hydroxy-3,4-dioxopentyl phosphate = 3-hydroxy-2,4- dioxopentyl phosphate; Xref=Rhea:RHEA:44360, ChEBI:CHEBI:71677, ChEBI:CHEBI:84359; EC=5.3.1.32;
SUBUNIT	Homodimer.
SUBCELLULAR LOCATION	Cytoplasm.
SIMILARITY	Belongs to the LsrG family.
