RPIA Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 331 amino acids (1-311) and having a molecular mass of 35.4kDa.RPIA is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Ribose-5-phosphate isomerase (RPIA) is a member of the ribose 5-phosphate isomerase family. RPIA is an enzyme which catalyzes the conversion between ribose-5-phosphate (R5P) and ribulose-5-phosphate (Ru5P). RPI occurs as 2 separate proteins forms, termed RPIA and RPIB. RPIA has a vital role in the metabolism of plants and animals, as it is involved in the Calvin cycle which takes place in plants, and the pentose phosphate pathway which occurs in plants as well as animals.
The RPIA solution (0.25mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 2mM DTT,40% glycerol, 200mM NaCl, 2mM EDTA and 0.2mM PMSF.
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles.
