DPH2 Homolog, S-Adenosyl-L-Methionine:L-Histidine 3-Amino-3-Carboxypropyltransferase 2, Diphtheria Toxin Resistance Protein 2, Diphthamide Biosynthesis Protein 2, DPH2L2, Diptheria Toxin Resistance Protein Required For Diphthamide Biosynthesis-Like 2, 2-(3-Amino-3-Carboxypropyl)Histidine Synthase Subunit 2, Diphthamide Biosynthesis Protein 2 Homolog-Like 2, Diphthamide Biosynthesis-Like Protein 2, EC 126.96.36.199, DPH2-Like 2, DPH2.
Diphthamide biosynthesis protein 2 (DPH2) is a homodimer and each of its monomers can bind a [4Fe-4S] cluster. DPH2 is the target of ADP ribosylating diphtheria toxin (DT) and Pseudomonas exotoxin A (PE). DPH2 was identified by its ability to complement a diphthamide mutant strain, and thus serves in diphthamide biosynthesis. The loss of DPH2 pre-activates NF-kB and death receptor pathways and renders MCF7 cells hypersensitive to tumor necrosis factor.
DPH2 Human Recombinant produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 497 amino acids (1-489a.a.) and having a molecular mass of 53.1kDa (Molecular size on SDS-PAGE will appear at approximately 50-70kDa). DPH2 is expressed with an 8 amino acids His tag at C-Terminus and purified by proprietary chromatographic techniques.
Sf9, Baculovirus cells.
DPH2 protein solution (0.5mg/ml) contains Phosphate Buffered Saline (pH 7.4), 1mM DTT and 20% glycerol.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 85.0% as determined by SDS-PAGE.
