Accepted name: (4S)-4-hydroxy-5-phosphooxypentane-2,3-dione isomerase
Reaction: (2S)-2-hydroxy-3,4-dioxopentyl phosphate = 3-hydroxy-2,4-dioxopentyl phosphate
Glossary: (2S)-2-hydroxy-3,4-dioxopentyl phosphate = (4S)-4-hydroxy-5-phosphooxypentane-2,3-dione
(4S)-4,5-dihydroxypentane-2,3-dione = autoinducer 2 = AI-2
Other name(s): lsrG (gene name); phospho-AI-2 isomerase; (4S)-4-hydroxy-5-phosphonooxypentane-2,3-dione aldose-ketose-isomerase; (4S)-4-hydroxy-5-phosphonooxypentane-2,3-dione isomerase; (4S)-4-hydroxy-5-phosphooxypentane-2,3-dione aldose-ketose-isomerase
Systematic name: (2S)-2-hydroxy-3,4-dioxopentyl phosphate aldose-ketose-isomerase
Comments: The enzyme participates in a degradation pathway of the bacterial quorum-sensing autoinducer molecule AI-2.
