Salmonella paratyphi B (strain ATCC BAA-1250 / SPB7)
Autoinducer 2-degrading protein lsrG
Short name= AI-2-degrading protein lsrG
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Involved in the degradation of phospho-AI-2, thereby terminating induction of the lsr operon and closing the AI-2 signaling cycle. Catalyzes the conversion of (4S)-4-hydroxy-5-phosphonooxypentane-2,3-dione (P-DPD) to 3-hydroxy-5-phosphonooxypentane-2,4-dione (P-HPD).
