MgtA leader peptide
Regulatory leader peptide for mgtA
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.
Makes mgtA transcription sensitive to intracellular proline levels. Under low levels of proline this protein cannot be fully translated, and a stem loop forms which permits transcription of the downstream mgtA gene (By similarity).
