    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(chǎn)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(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 beta sliding clamp loading complex, which hydrolyzes ATP to load the beta clamp onto primed DNA to form the DNA replication pre-initiation complex. DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3'-5' exonuclease activity. The gamma complex (gamma(3),delta,delta') is thought to load beta dimers onto DNA by binding ATP which alters the complex's conformation so it can bind beta sliding clamp dimers and open them at one interface. Primed DNA is recognized, ATP is hydrolyzed releasing the gamma complex and closing the beta sliding clamp ring around the primed DNA.; serves as a scaffold to trimerize the core complex.; interacts with the delta and delta' subunits to transfer the beta subunit on the DNA. Interacts with ATP, drives ATP-induced conformational changes in the gamma complex that opens the beta sliding clamp ring. After loading of primed DNA ATP is hydrolyzed and the beta sliding clamp ring closes.

    1. study characterized the dnaXE145A clamp loader mutant; found that the naturally occurring obstacles encountered by a replication fork are not tackled in a proper way by the mutant clamp loader and suggest a role for the clamp loader in the restart of stalled replication forks PMID: 28947673
    2. Ribosome frameshifting during translation of bacterial dnaX can proceed via different routes, generating a variety of distinct polypeptides. PMID: 28525745
    3. Data show that expression from DNA polymerase III dnaX to produce gamma subunit is essential for normal cellular function. PMID: 26786318
    4. Destabilization of the single-stranded DNA-chi subunit of DNA polymerase III complex in vivo produces cells with temperature- dependent cell cycle defects that appear to arise from replisome instability. PMID: 21857649
    5. Analyzing DnaX complexes containing one or more K51E variant DnaX subunits demonstrated that only one active ATP binding site is required to form initiation complexes, but the two additional sites increase the rate by ca 1000-fold. PMID: 21820444
    6. Only one ATP-binding DnaX subunit is required for initiation complex formation by the Escherichia coli DNA polymerase III holoenzyme. PMID: 20675375
    7. tau subunit plays an important role in determining the fidelity of the chromosomal replication, specifically in the avoidance of transversions and frameshift mutations. PMID: 16430690
    8. data suggest that the unstructured C-terminus of tau subunit of Escherichia coli DNA polymerase III holoenzyme becomes folded into a helix-loop-helix in its complex with alpha subunit. PMID: 17355988
    9. The interaction site of protein domains of of the tau subunit of Escherichia coli DNA polymerase III on the alpha subunit was mapped by NMR experiments. PMID: 17452361
    10. Data support the assumption that dnaX36-mediated mutations originate as errors of replication rather than DNA damage-related events. PMID: 18156258
    11. The DNA polymerase III clamp loading reaction can be divided into two stages: formation of a ternary clamp loader.clamp.DNA complex, and decay of the ternary complex to produce a clamp.DNA complex. Clamp release is likely to be the rate-limiting step. PMID: 19663416
