IDI1, Human

(Isopentenyl-diphosphate Delta-isomerase 1, Isopentenyl pyrophosphate isomerase 1, IPP isomerase 1, IPPI1, IDI1, IPP1.)

Isopentenyl-diphosphate isomerase 1 (IDI1) belongs to the IPP isomerase type I family and is involved in cholesterol biosynthesis. IDI1 is a peroxisomally-localized enzyme which catalyzes the interconversion of isopentenyl diphosphate (IPP) to its highly electrophilic isomer, dimethylallyl diphosphate (DMAPP), which is the substrate for the sequential reaction that results in the synthesis of farnesyl diphosphate and, eventually, cholesterol. Peroxisomal deficiency diseases such as Zellweger syndrome and neonatal adrenoleukodystrophy show a reduction in IPP isomerase activity.

IDI1 Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 248 amino acids (1-228) and having a molecular mass of 28.6kDa. IDI1 is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

Purity: Greater than 90% as determined by SDS-PAGE.

Source: E.coli.

Physical Appearance: Sterile Filtered colorless solution.

Formulation: The IDI1 solution (1mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 1mM DTT, 10% glycerol and 0.1M NaCl.
