    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.

  • 蛋白标签：
    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.
  • 产品提供形式：
    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.
  • 复溶：
    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.
  • 储存条件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保质期：
    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.
  • 货期：
    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.
  • 注意事项：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • Datasheet ：

  • 功能：
    Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. R1 contains the binding sites for both substrates and allosteric effectors and carries out the actual reduction of the ribonucleotide. It also provides redox-active cysteines.

    1. Elimination of 6 helicases lowered NrdA production further, whereas overexpression of any RNA helicase partially reversed the downregulation. UV stress completely reversed down-regulation of NrdA production PMID: 26574793
    2. The present results identifying a large, new set of E. coli mutator strains with mutations of nrdAB ribonucleotide reductase(RNR)confirm the important control that RNR exerts on the cellular mutation rate and provide novel insights into the RNR feedback regulatory mechanisms. PMID: 22417940
    3. RNR101 is unstable at 42 degrees C ; its degradation is prevented by rifampicin; inactivation of DnaA protein by allows chromosome replication in absence of rifampicin and suppresses nucleoid segregation and cell division defects seen in nrdA101 mutant at 42 degrees C PMID: 21527473
    4. The report three independent methods that establish that Y(356) is the predominant location (85-90%) of the radical, with the remaining 10-15% delocalized onto Y(731) and Y(730) in alpha2. PMID: 21967342
    5. The s propose that RecA is required to maintain the integrity of the reversed forks in the nrdA101 mutant under certain restrictive conditions, supporting the relationship between DNA replication and recombination enzymes. PMID: 21441507
    6. The s show that the binding of DnaA on the NrdAB promoter can either activate or repress transcription as a function of its concentration and its nucleotide-bound state. PMID: 20487274
    7. analysis of key residues in the dimerization process of ribonucleotide reductase protein R1 PMID: 15699052
    8. There is an indirect relationship between NDP reductase and the chromosome segregation machinery through the maintenance of the proposed replication hyperstructure. PMID: 17124544
    9. it is proposed that an altered NDP reductase, as a component of the replication machinery, impairs the progression of the replication fork, contributing to the lengthening of the C period in the nrdA101 mutant at the permissive temperature PMID: 17322311
