Fructose-1,6-bisphosphatase 1, FBPase 1, D-fructose-1,6-bisphosphate 1-phosphohydrolase 1, Liver FBPase, FBP1, FBP.
FBP1 or Fructose-1, 6-bisphosphatase 1 is an enzyme, catalyzing the formation of fructose 6-phosphate & inorganic phosphate from fructose 1, 6-bisphosphate. FBP1 is part of the gluconeogenesis regulatory enzymes. Mutations in the enzyme gene can result in metabolic acidosis & hypoglycemia.
FBP1 Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 358 amino acids (1-338) and having a molecular mass of 39.0 kDa.
FBP1 is fused to a 20 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques.
FBP1 protein solution (1mg/ml) contains 1mM DTT, 10% glycerol and 20mM Tris-HCl buffer (pH 8.0).
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 90.0% as determined by SDS-PAGE.
Specific activity is > 7,000pmol/min/ug, and is determined by measuring the increase of NADPH in absorbance at 340 nm resulting from the reduction of NADP. 1 unit oxidizes 1.0pmole of fructose 1,6 diphosphate to fructose 6- phosphate and inorganic phosphate per minute at pH 9.5 at 37˚C.
