Bifunctional protein pyrR
Including the following 2 domains:
Pyrimidine operon regulatory protein
Short name= UPRTase
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.
Regulates the transcription of the pyrimidine nucleotide (pyr) operon in response to exogenous pyrimidines.
