(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.
Based on the SEQUEST from database of E.coli host and target protein, the LC-MS/MS Analysis result of CSB-EP356423BUA could indicate that this peptide derived from E.coli-expressed Bordetella pertussis (strain Tohama I / ATCC BAA-589 / NCTC 13251) ptxA.

蛋白標簽:
N-terminal 6xHis-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.
S1 is an NAD-dependent ADP-ribosyltransferase, which plays a crucial role in the pathogenesis of B.pertussis causing disruption of normal host cellular regulation. It catalyzes the ADP-ribosylation of a cysteine in the alpha subunit of host heterotrimeric G proteins. In the absence of G proteins it also catalyzes the cleavage of NAD(+) into ADP-ribose and nicotinamide. It irreversibly uncouples the G-alpha GTP-binding proteins from their membrane receptors.
基因功能參考文獻:
It has been proposed that it is the systemic activity of pertussis toxin and not pulmonary pathology that promotes mortality in critical pertussis. PMID: 28784932
亞細胞定位:
Secreted. Note=The individual chains are secreted by a sec-dependent mechanism into the periplasm. Then, S1 associates with the outer membrane before it joins with the B subunit to form the secretion-competent holotoxin. The type IV secretion system ptl mediates secretion of assembled toxin through the outer membrane.
