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-SUMO-tagged
產品提供形式：

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.
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.

靶點詳情

功能：

The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing. RuvA stimulates, in the presence of DNA, the weak ATPase activity of RuvB. Binds both single- and double-stranded DNA (dsDNA). Binds preferentially to supercoiled rather than to relaxed dsDNA.
基因功能參考文獻：
1. Regression of replication forks stalled by leading-strand template damage: both RecG and RuvAB catalyze regression, but RuvC cleaves the holliday junctions formed by RecG preferentially. PMID: 25138216
2. These results suggest that RecQ acts upstream of RuvABC, RecG and XerC proteins, a finding that is compatible with its primary role in initiation of the RecF recombination pathway. PMID: 24036154
3. RNA polymerase mutations reduce the synergism between priB and ruvABC. PMID: 22957744
4. DNA fragmentation absolutely depends on both RecA-catalyzed homologous strand exchange and RuvABC-catalyzed Holliday junction resolution PMID: 22194615
5. Role in converting the initial single-strand DNA-protein cleavage complex into a double-strand break prior to repair by homologous recombination. PMID: 20601468
6. Study hypothesized that RuvAB catalyzes replication fork reversal in order to produce SOS(Con) expression. PMID: 20304994
7. RuvA octamerization is essential for the full biological activity of RuvABC. PMID: 15556943
8. RuvA is less mobile at a heterologous junction compared to a homologous junction, as two opposing DnaB pumps are required to mobilize RuvA over heterologous DNA. PMID: 16324713
9. RuvABC is required to resolve junctions that arise during the repair of a subset of nonarresting lesions after replication has passed through the template PMID: 16895921
10. The authors present here the isolation and characterization of ruvA and ruvB single mutants that are impaired for replication fork reversal at forks arrested by the inactivation of polymerase III, while they remain capable of homologous recombination. PMID: 18942176
