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：

N-terminal 6xHis-tagged
產品提供形式：

Liquid or 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.
緩沖液：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
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：

3-7 business days
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

功能：

Involved in the RecF recombination pathway; its gene expression is under the regulation of the SOS system. It is a DNA helicase.
基因功能參考文獻：
1. To illustrate the single-molecule unwinding assay and the analysis routine, we provide DNA unwinding measurements of Escherichia coli RecQ helicase under a variety of conditions (Na+, ATP, temperature, and DNA substrate geometry). PMID: 27131595
2. Data show that the single-stranded DNA binding protein (SSB)-RecQ helicase (RecQ) interaction changes the binding mode of SSB, thereby allowing RecQ to gain access to ssDNA and facilitating DNA unwinding. PMID: 29059328
3. the mechanochemical coupling of E. coli RecQ appears to be independent of HRDC-ssDNA and HRDC-RecA core interactions, which may play roles in more specialized functions of the enzyme. PMID: 26067769
4. Thus, bacterial type 1A topos maintain the stability of the genome (i) by preventing over-replication originating from oriC (topo I alone) and R-loops and (ii) by acting with RecQ. PMID: 25102178
5. The study found that the interaction of RecQ with DNA results in a drastic acceleration of the rate-limiting ATP cleavage step, which occurs productively due to subsequent rapid phosphate release. PMID: 25539922
6. The results shed light on the nature of conformational changes leading to processive ssDNA translocation and multistranded DNA processing by RecQ helicases. PMID: 24403069
7. Results describe the mechanism of DNA unwinding by the Escherichia coli RecQ helicase using a new sensitive helicase assay based on fluorescence cross-correlation spectroscopy (FCCS) with two-photon excitation. PMID: 20048388
8. The aromatic-rich loop in RecQ is critical for coupling ATPase and DNA-binding/unwinding activities. PMID: 16340008
9. E.coli RecQ functions as a monomer and some of the Superfamily 2 helicases may function through an "inchworm" mechanism PMID: 16507576
10. RecQ promotes the net accumulation of bimolecular recombination intermediates in vivo, indicating a second paradigm for the in vivo effect of RecQ-like proteins. PMID: 17466628
11. SSB is a broadly conserved RecQ-binding protein PMID: 17483090
12. These results support a model in which RecQ has evolved an SSB-C-terminal binding site on its winged-helix domain as an adaptation that aids its cellular functions on SSB/DNA nucleoprotein substrates. PMID: 19150358
