EC 2.7.1.189

Accepted name: autoinducer-2 kinase

Reaction: ATP + (S)-4,5-dihydroxypentane-2,3-dione = ADP + (S)-4-hydroxypentane-2,3-dione 5-phosphate

Glossary: (S)-4,5-dihydroxypentane-2,3-dione = autoinducer 2 = AI-2

Other name(s): lsrK (gene name)

Systematic name: ATP:(S)-4,5-dihydroxypentane-2,3-dione 5-phosphotransferase

Comments: The enzyme participates in a degradation pathway of the bacterial quorum-sensing autoinducer molecule AI-2.
