    Note: The complete sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
    If the exact amino acid sequence of this recombinant protein is critical to your application, please explicitly request the full and complete sequence of this protein before ordering.
  • 蛋白標簽：
    C-terminal 6xHis-tagged
  • 產(chǎn)品提供形式：
    Liquid or 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.
  • 緩沖液：
    If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
  • 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(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：
    3-7 business days
  • 注意事項：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
  • Datasheet & COA：

靶點詳情

  • 功能：
    AcrA-AcrB-AcrZ-TolC is a drug efflux protein complex with broad substrate specificity that uses the proton motive force to export substrates. This subunit may act as an adapter protein that links AcrB and TolC stably together. It is elongated in shape, being long enough to span the periplasm.
  • 基因功能參考文獻：
    1. The results underscore the importance of the periplasmic turn 1 of TolC in the functional assembly of the tripartite efflux complex and AcrA in transitioning TolC from its closed to open state. PMID: 20132445
    2. Our results indicate functional interactions between the AcrA -hairpin tip region and the TolC aperture tip region in the assembly of the functional tripartite efflux pump AcrAB-TolC. PMID: 20581201
    3. Data show that the AcrA-mediated suppression of mutant TolC phenotypes and stabilization of mutant TolC were dependent on AcrB, reflecting the existence of a functional complex between TolC and AcrAB in vivo. PMID: 15491355
    4. TolC-AcrA interaction demonstrated via cross-linking studies PMID: 15576805
    5. The observed pulsating behavior in inducible transcription of acrA is a systems property arising from the dependence of gene expression on multidrug resistance determinants. PMID: 16461398
    6. AcrS represses the gene expression of multidrug efflux genes, acrA and acrB PMID: 18567659
    7. Data suggest that recruitment of TolC by various MFPs AcrA, MacA, and EmrA is determined not only by kinetics of MFP-TolC interactions but also by oligomerization kinetics of MFPs and pH. PMID: 19805313
