    Avi-tag Biotinylated

    E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

    The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
  • 產品提供形式：
    Lyophilized powder Warning: in_array() expects parameter 2 to be array, null given in /www/web/cusabio_cn/public_html/caches/caches_template/default/content/show_product_protein.php on line 662
    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.
  • 復溶：
    We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
  • 儲存條件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保質期：
    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.
  • 貨期：
    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.
  • 注意事項：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • Datasheet ：

靶點詳情

  • 功能：
    Conjugative DNA transfer (CDT) is the unidirectional transfer of ssDNA plasmid from a donor to a recipient cell. It is the central mechanism by which antibiotic resistance and virulence factors are propagated in bacterial populations. Part of the relaxosome, which facilitates a site- and strand-specific cut in the origin of transfer by TraI, at the nic site. Relaxosome formation requires binding of IHF and TraY to the oriT region, which then facilitates binding of TraI relaxase. TraI forms a covalent 5'-phosphotyrosine intermediate linkage to the ssDNA. The transesterified T-strand moves from the donor cell to the recipient cell in a 5'to 3' direction, with the DNA helicase activity of TraI unwinding the DNA. DNA transfer occurs via the conjugative pore (transferosome) an intercellular junction mediated by a type IV secretion system, with TraD providing the means to link the relaxosome to the conjugative pore. The relaxase completes DNA transfer by reversing the covalent phosphotyrosine linkage and releasing the T-strand.; TraI has also been identified as DNA helicase I. DNA. helicase I is a potent, highly processive DNA-dependent ATPase, able to unwind about 1.1 kb dsDNA per second in a 5' to 3' manner.

This structure was solved with a 22-mer oriT T-strand DNA and represents TraI in its "helicase" mode. PMID: 28457609
