CC   -!- FUNCTION: Involved in the degradation of phospho-AI-2, thereby
CC       terminating induction of the lsr operon and closing the AI-2 signaling
CC       cycle. Catalyzes the conversion of (4S)-4-hydroxy-5-
CC       phosphonooxypentane-2,3-dione (P-DPD) to 3-hydroxy-5-
CC       phosphonooxypentane-2,4-dione (P-HPD). {ECO:0000255|HAMAP-
CC       Rule:MF_02051}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2S)-2-hydroxy-3,4-dioxopentyl phosphate = 3-hydroxy-2,4-
CC         dioxopentyl phosphate; Xref=Rhea:RHEA:44360, ChEBI:CHEBI:71677,
CC         ChEBI:CHEBI:84359; EC=5.3.1.32; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_02051};
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_02051}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_02051}.
CC   -!- SIMILARITY: Belongs to the LsrG family. {ECO:0000255|HAMAP-
CC       Rule:MF_02051}.
