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.
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.
產(chǎn)品提供形式:
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.
復(fù)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(chǔ)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:
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.
注意事項(xiàng):
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點(diǎn)詳情
功能:
Catalyzes the covalent attachment of ubiquitin to other proteins. Capable, in vitro, to ubiquitinate histone H2A.; Mediates the initiation of DNA replication (transition of G1 to S phase in cell cycle). Essential component of the E3 ubiquitin ligase complex SCF (SKP1-CUL1-F-box protein), which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Involved in the regulation of methionine biosynthesis genes and in the degradation of CDC6 together with CDC4 and CDC53.
基因功能參考文獻(xiàn):
Cdc34 phosphorylation by PKA and Sch9 provides a direct tether between G1 cell division events and cell growth PMID: 22087249
Cdc34 showed a strong preference for Ub lysine 48 (K48), with lower activity towards lysine 11 (K11) and lysine 63 (K63). PMID: 23656784
chromosome segregation in cdc6 mutant is caused by the deregulation of spindle dynamics induced via a regulatory network involving the ubiquitin-conjugating enzyme Cdc34, microtubule-associated proteins and the anaphase-promoting complex activator Cdh1. PMID: 22805765
Cdc34 is particularly sensitive to oxidative inactivation, through sequestration of the catalytic cysteine in a disulfide complex with Uba1, by levels of oxidant that do not reduce global ubiquitinylation of proteins. PMID: 22949505
Through analysis of the phenotype of a mutant missing a highly conserved sequence motif within the catalytic domain of Cdc34, we discovered previously unrecognized levels of regulation PMID: 21196523
Data show that proximal amino acids surrounding the lysine residues in Sic1 and Ub are critical for ubiquitination, and that this mechanism is linked to key residues composing the catalytic core of Cdc34 and independent of SCF. PMID: 20194622
The acidic loop of CDC34 favorably positions K48 of a substrate-linked ubiquitin to attack SCF bound Cdc34-ubiquitin thioester and thereby enables processive synthesis of K48-linked ubiquitin chains by SCF-Cdc34. PMID: 16360039
We propose that interactions between Cdc34 approximately Ub and SCF directly activate ubiquitin transfer within a substrate-SCF-Cdc34 approximately Ub ternary complex. PMID: 17114057
studies demonstrate that CK2-mediated phosphorylation of Cdc34 on the acidic tail domain stimulates Cdc34-SCFCdc4 ubiquitination activity and cell cycle progression PMID: 17461777
In in vitro experiments with single-lysine-containing Cdc34 mutant proteins of Saccharomyces cerevisiae, the SCF-mediated stimulation of autoubiquitination is limited to specific N-terminal lysines modified via an intermolecular mechanism. PMID: 17562869
The CK2 phosphorylation of catalytic domain of Cdc34 modulates its activity at the G1 to S transition in Saccharomyces cerevisiae. PMID: 18418079
The acidic tail of the Cdc34 ubiquitin-conjugating enzyme functions in both binding to and catalysis with ubiquitin ligase SCFCdc4. PMID: 19875449
