    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(chǔ)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：
    Part of the processive rRNA transcription and antitermination complex (rrnTAC). The complex forms an RNA-chaperone ring around the RNA exit tunnel of RNA polymerase (RNAP). It supports rapid transcription and antitermination of rRNA operons, cotranscriptional rRNA folding, and annealing of distal rRNA regions to allow correct ribosome biogenesis. Participates in transcription elongation, termination and antitermination. In the absence of Rho, increases the rate of transcription elongation by the RNAP, probably by partially suppressing pausing. In the presence of Rho, modulates most Rho-dependent termination events by interacting with the RNAP to render the complex more susceptible to the termination activity of Rho. May be required to overcome a kinetic limitation of Rho to function at certain terminators. Also involved in ribosomal RNA and phage lambda N-mediated transcriptional antitermination.
  • 基因功能參考文獻(xiàn)：
    1. The comprehensive mapping of the upstream fork junction by base analogue fluorescence and nucleic acids crosslinking suggests that NusG inhibits backtracking by stabilizing the minimal transcription bubble. PMID: 27697152
    2. NusG acts as both a positive and a negative regulator of Rho in the course of the bacterial transcription termination. (Review) PMID: 27023849
    3. NusG is required for efficient termination at minority subsets (~20%) of both antisense and sense Rho-dependent terminators with lower C/G ratio sequences PMID: 23207917
    4. E. coli NusG inhibits backtracking and accelerates pause-free transcription by promoting forward translocation of RNA polymerase. PMID: 20381500
    5. findings suggest that the mini-domain serves as a structural element for an interaction rather than as a site for residue-specific contacts PMID: 15890417
