  • 蛋白标签：
    N-terminal 10xHis-tagged
  • 产品提供形式：
    Liquid or Lyophilized powder
    Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
  • 缓冲液：
    Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0
  • 储存条件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保质期：
    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.
  • 货期：
    Basically, we can dispatch the products out in 1-3 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
    Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
  • 注意事项：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

  • 功能：
    Subunit of the protein translocation channel SecYEG. Overexpression of some hybrid proteins has been thought to jam the protein secretion apparatus resulting in cell death; while this may be true it also results in FtsH-mediated degradation of SecY. Treatment with antibiotics that block translation elongation such as chloramphenicol also leads to degradation of SecY and SecE but not SecG.

    1. s show that SecG plays a critical role for the residual export mediated by mutant signal sequences and that the SecYE dimer can often be detected only in the presence of SecG. PMID: 25404704
    2. The hydrophobicity threshold for SecYEG-mediated cell membrane insertion is distinctly lower than that for Sec61-mediated insertion. PMID: 23659793
    3. Data show that ribosome binding is sufficient to open the SecYEG channel. PMID: 23645666
    4. Data indicate taht SecG inversion occurs only when MPIase associates with SecYEG. PMID: 23716687

    9. cotranslational targeting of a protein to the E. coli SecYEG complex does not ensure its export but that export also depends on a subsequent event that involves sequences both within and just beyond the signal peptide PMID: 19211555
