  • 共軛：
    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.

靶點詳情

  • 功能：
    Involved in UV protection and mutation. Poorly processive, error-prone DNA polymerase involved in translesion repair. Essential for induced (or SOS) mutagenesis. Able to replicate DNA across DNA lesions (thymine photodimers and abasic sites, called translesion synthesis) in the presence of activated RecA; efficiency is maximal in the presence of the beta sliding-clamp and clamp-loading complex of DNA polymerase III plus single-stranded binding protein (SSB). RecA and to a lesser extent the beta clamp-complex may target Pol V to replication complexes stalled at DNA template lesions.
  • 基因功能參考文獻：
    1. There are multiple levels of regulation imposed on pol V including transcriptional control, posttranslational modification, targeted proteolysis, activation of the catalytic activity of pol V through protein-protein interactions and the very recently described intracellular spatial regulation of pol V. (Review) PMID: 27236212
    2. The current study delves deeper into this process, initiating the task of mapping out the molecular details of the interaction between RecA and UmuD'2C PMID: 25811184
    3. Like the self-cleaving serine proteases LexA and UmuD in Escherichia coli, UmuDAb required RecA for cleavage. PMID: 22697494
    4. Electron paramagnetic resonance (EPR) spectroscopy study determined that the arms of UmuD2 display a large degree of motion, are largely unbound from the globular C-terminal domain, and that the free energy of dissociation is 2.1 kJ mol-1 PMID: 21975937
    5. Study find that mutations of the N-terminal residues of loop 1, N32, N33, and D34, confer hypersensitivity to UV radiation and to 4-nitroquinoline-N-oxide and significantly reduce Pol V-dependent UV-induced mutagenesis. PMID: 21784925
    6. Wild-type UmuD(2) and UmuD'(2) form exceptionally tight dimers in solution; however, we show that the single amino acid change N41D generates stable, active UmuD and UmuD' monomers that functionally mimic the dimeric wild-type proteins. PMID: 21118802
    7. REVIEW: properties and functions of Pol V PMID: 15588845
    8. In the absence of repair or when the repair capacity of the cell has been exceeded, translesion synthesis by polymerase V (Pol V) allows DNA synthesis to resume and is required to protect the arrested replication fork from degradation. PMID: 16199565
    9. Lyase activity intrinsic to polymerase V PMID: 16202661
    10. AlkB dioxygenase, PolV (UmuD'C), and AlkA have roles in preventing MMS-induced mutagenesis in Escherichia coli PMID: 16226494
    11. found new class of UmuD variant proteins that fail to undergo cleavage but whose properties resemble those of the cleaved version, UmuD' PMID: 16464848
    12. Structural characteristics of relatively poorly understood, intrinsically disordered umuD small dimeric proteins provide a model for the regulation of diverse aspects of the bacterial SOS response. PMID: 18216271
