Conjugate 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.

Tag Info
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.
Form
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.
Buffer before Lyophilization
Tris/PBS-based buffer, 6% Trehalose, pH 8.0
Reconstitution
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.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
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.
Lead Time
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.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
Specifically hydrolyzes both 8-oxo-deoxyguanosine triphosphate (8-oxo-dGTP) and 8-oxo-guanosine triphosphate (8-oxo-GTP) to the related monophosphates, thereby cleaning up the nucleotide pools and preventing misincorporation of 8-oxoGua into DNA and RNA. It prevents replicational errors by removing an oxidatively damaged form of guanine (8-oxo-dGTP) from DNA and the nucleotide pool. 8-oxo-dGTP can be inserted opposite dA and dC residues of template DNA with almost equal efficiency thus leading to A.T to G.C transversions. MutT may also ensure transcriptional fidelity, removing 8-oxo-GTP from the ribonucleotide triphosphate pool. However, due to the lower efficiency of RNA polymerase 8-oxo-GTP incorporation, MutT is probably not a major contributor to transcriptional fidelity. It also hydrolyzes 8-oxo-dGDP and 8-oxo-GDP to their monophosphate form. In vitro, can also use dGTP, dGDP and other various nucleoside di- and triphosphates, with much lower efficiency. Works cooperatively with MutM and MutY to prevent accumulation in the DNA of oxidized guanine residues.
Gene References into Functions
  1. The study investigated the role of MutT on transcription fidelity and find no increase in epigenetic switch frequency in the absence of MutT function. PMID: 25294823
  2. MutT mutation increased the point-mutation rate 150-fold. PMID: 23248287
  3. The MutT functions are not needed under anaerobic condition, yet the level of the MutT protein in cell is kept constant, probably for preparing for sudden changes of oxygen pressure. PMID: 21147134
  4. MutT hydrolyzes four types of 8-oxoGua (8-oxo-7,8-dihydroguanine)-containing nucleoside diphosphates and triphosphates to the related monophosphates, thereby preventing misincorporation of 8-oxoGua into DNA and RNA. PMID: 15850400
  5. transient state kinetic analysis of the reaction pathway of mutT; findings confirm an iso kinetic mechanism and explain the preferred hydrolysis of 8-oxo-dGTP PMID: 16285737
  6. These results indicate that mutT plays important roles in mutagenesis induced by 2-OH-dATP and 8-OH-dGTP in vivo. PMID: 17150583
  7. The mutT defect does not elevate chromosomal fragmentation in Escherichia coli because of the surprisingly low levels of MutM/MutY-recognized DNA modifications. PMID: 17616589
