DESCRIPTION

Also known as LSRK_SALPA, lsrK. Catalyzes the phosphorylation of autoinducer-2 (AI-2) to phospho-AI-2, which subsequently inactivates the transcriptional regulator LsrR and leads to the transcription of the lsr operon. Phosphorylates the ring-open form of (S)-4, 5-dihydroxypentane-2, 3-dione (DPD), which is the precursor to all AI-2 signaling molecules, at the C5 position.
