    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.

  • 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.

  • 功能：
    Essential cell division protein that coordinates cell division and chromosome segregation. The N-terminus is involved in assembly of the cell-division machinery. The C-terminus functions as a DNA motor that moves dsDNA in an ATP-dependent manner towards the dif recombination site, which is located within the replication terminus region. Translocation stops specifically at Xer-dif sites, where FtsK interacts with the Xer recombinase, allowing activation of chromosome unlinking by recombination. FtsK orienting polar sequences (KOPS) guide the direction of DNA translocation. FtsK can remove proteins from DNA as it translocates, but translocation stops specifically at XerCD-dif site, thereby preventing removal of XerC and XerD from dif. Stoppage of translocation is accompanied by a reduction in ATPase activity. Also stimulates topoisomerase 4 activity. Required for the targeting of FtsQ, FtsL and FtsI to the septum.

    1. FtsKgamma interacts with the C-terminal domain of XerD, above a cleft where XerC is thought to bind. We present a model for activation of recombination based on structural data. PMID: 27708355
    2. We found that whatever the growth conditions, sister copies of the V. cholerae chr1 dif region remain together at mid-cell until the onset of constriction, which permits their processing by FtsK and the activation of dif-recombination. PMID: 28358835
    3. FtsK translocase has a role in assembly, translocation, and activation of XerCD-dif recombination PMID: 26324908

    11. FtsK translocation stops specifically at XerCD-dif, thereby preventing removal of XerCD from dif and allowing activation of chromosome unlinking by recombination. PMID: 19854947
    12. Data describe the in vivo effects of deletions of FtsK(L) and/or of FtsK(C), of swaps of these domains with their Haemophilus influenzae counterparts and of a point mutation that inactivates the walker A motif of FtsK(C). PMID: 15522074
    13. directly observed the movement of purified FtsK on single DNA molecules; results imply that FtsK is a bidirectional motor that changes direction in response to short, asymmetric directing DNA sequences PMID: 15681387
    14. FtsK induces approximately 0.07 supercoils per DNA helical pitch traveled PMID: 15821742
    15. translocation by FtsK occurs mostly on DNA belonging to a specifically organized domain of the chromosome, when physical links between either dimeric or still intercatenated chromosomes force this DNA to run across the septum at division PMID: 15916604
    16. Results suggest that the N-terminal domain of FtsK is normally involved in stability of the division protein machine and shares functional overlap with FtsQ, FtsB, FtsA, ZipA and FtsN. PMID: 16194242
    17. FtsK translocase is a powerful motor that is able to displace a triplex-forming oligo from a DNA substrate PMID: 16301526
