    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(biāo)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(chǎn)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(fù)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(zhì)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.

靶點詳情

  • 功能：
    DEAD-box RNA helicase involved in the assembly of the 50S ribosomal subunit. Has an RNA-dependent ATPase activity, which is specific for 23S rRNA, and a 3' to 5' RNA helicase activity that uses the energy of ATP hydrolysis to destabilize and unwind short rRNA duplexes. Requires a single-stranded RNA loading site on the 3' side of the substrate helix.
  • 基因功能參考文獻：
    1. Overexpression of the inactive DbpA R331A mutant appears to block assembly at a late stage when the peptidyl transferase center is formed, indicating a possible role for DbpA promoting this conformational change. PMID: 19734347
    2. ADP binding increases the conformational flexibility and dynamics of DbpA PMID: 15654752
    3. The directionality of helicase activity of DbpA has been determined; DbpA is defined as a 3'-> 5' helicase. PMID: 15910005
    4. results favor models where DbpA functions as an active monomer that possesses two distinct RNA binding sites, one in the helicase core domain and the other in the carboxyl-terminal domain PMID: 16325852
    5. Identification of dominant-negative mutant form of DbpA that results in a slow growth phenotype. PMID: 17986459
    6. The presented analysis of the DbpA ATPase cycle reaction mechanism provides a rigorous kinetic and thermodynamic foundation for developing testable hypotheses regarding the functions and molecular mechanisms of DEAD-box helicases. PMID: 18237742
