    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(xiàng)：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • Datasheet ：

靶點(diǎn)詳情

  • 功能：
    Involved in the transmission of sensory signals from the chemoreceptors to the flagellar motors. CheA is autophosphorylated; it can transfer its phosphate group to either CheB or CheY.
  • 基因功能參考文獻(xiàn)：
    1. Signaling complexes control CheA by altering its apparent rate constant of autophosphorylation. PMID: 28425142
    2. Differences were observed, however, in a keel-like density that we identify here as CheA kinase domains P1 and P2, the phosphorylation site domain and the binding domain for response regulator target proteins. PMID: 23802570
    3. Thus, these P1 phosphorylation domain mutants appear to define interaction determinants for P1-P4 docking during the CheA autophosphorylation reaction. PMID: 24163342
    4. crystal of CheA belonged to space group P1, with unit-cell parameters a = 59.271, b = 67.674, c = 82.815 A, alpha = 77.568, beta = 86.073, gamma = 64.436 degrees . The asymmetric unit may contain up to ten dimeric units of P3 four-helix bundles PMID: 21636905
    5. The fluorescence properties of CheA carrying a Phe455Trp replacement can be used to monitor ATP-binding events and a conformational change at the CheA protein histidine kinase active site. PMID: 15766267
    6. Results describe the ranges and kinetics of domain motions in the free CheA dimer. PMID: 19256549
    7. Specific CheA-short (CheA(S)) residues, L123 and L126, were identified as critical for CheZ binding. In the CheA(S) 'P1-CheZ nuclear magnetic resonance structure, these residues form an interaction surface on alpha-helix E in the 'P1 domain. PMID: 19581362
