SKU:: 518103
Molecular Weight:: 29.3
Purity:: ≥85% (SDS-PAGE)
Storage Conditions:: -20°C
Supplier:: United States Biological
Format:: Supplied as a lyophilized powder from 20mM Tris-HCl, 0.5M sodium chloride, pH 8.0, 6% trehalose. Reconstitute with sterile ddH2O to a concentration of 0.1-1mg/ml.
Extra Details:: Member of the two-component regulatory system WalK/WalR that regulates genes involved in autolysis, biofilm formation and cell wall metabolism. WalK functions as a sensor protein kinase which is autophosphorylated at a histidine residue and transfers its phosphate group to WalR. Source: Partial recombinant protein corresponding to aa382-600 of Staphylococcus aureus Sensor Protein Kinase WalK, fused to 10xHis-Tag at N-terminal and Myc-Tag at C-terminal, expressed in E. coli.
