    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.

  • 蛋白標簽：
    Tag?type?will?be?determined?during?the?manufacturing?process.
    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
    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 ：
    Please contact us to get it.

產品評價

靶點詳情

  • 功能：
    Catalyzes the conversion of dethiobiotin (DTB) to biotin by the insertion of a sulfur atom into dethiobiotin via a radical-based mechanism.
  • 基因功能參考文獻：
    1. In biotin synthase, abstraction of a hydrogen atom from the C9 methyl group of dethiobiotin results in formation of a dethiobiotinyl methylene carbon radical, which is quenched by a sulfur atom to form a new carbon-sulfur bond in 9-mercaptodethiobiotin. PMID: 21859080
    2. Asparagine 153 and aspartate 155 of bioB are important for retaining intermediates during the catalytic cycle. PMID: 19199517
    3. mutants of highly conserved residues from the Y(150)NHNLD motif are inactive & are also unable to cleave AdoMet and to produce the deoxyadenosyl radical (AdoCH(2)(*)). PMID: 17014080
    4. It is proposed that the [2Fe-2S]2+ cluster of biotin synthase is both the sulfur-donating substrate and the sulfur-oxidizing cofactor, but each round of catalysis generates an inactive enzyme in which this cluster has been destroyed. PMID: 18155152
    5. mutations in the conserved YNHNLD sequence of Escherichia coli BioB affect the formation and stability of the [4Fe-4S](1+) cluster on reduction with dithionite and report the observation of a new [2Fe-2S](1+) cluster. PMID: 19245793
