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.
