CC   -!- FUNCTION: Catalyzes the phosphorylation of autoinducer-2 (AI-2) to
CC       phospho-AI-2, which subsequently inactivates the transcriptional
CC       regulator LsrR and leads to the transcription of the lsr operon.
CC       Phosphorylates the ring-open form of (S)-4,5-dihydroxypentane-2,3-dione
CC       (DPD), which is the precursor to all AI-2 signaling molecules, at the
CC       C5 position. {ECO:0000255|HAMAP-Rule:MF_02053}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(S)-4,5-dihydroxypentane-2,3-dione + ATP = (2S)-2-hydroxy-3,4-
CC         dioxopentyl phosphate + ADP + H(+); Xref=Rhea:RHEA:15377,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:29484, ChEBI:CHEBI:30616,
CC         ChEBI:CHEBI:71677, ChEBI:CHEBI:456216; EC=2.7.1.189;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_02053};
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_02053}.
CC   -!- SIMILARITY: Belongs to the FGGY kinase family. {ECO:0000255|HAMAP-
CC       Rule:MF_02053}.
