Merck, P2621-2MG, Phosphomannose Isomerase from Escherichia coli

Application
PMI is used to study cell wall synthesis and energy production. PMI has been used to study how EDTA and metal ions, such as Zn++, Co++, Fe++, Mn++ and Cu++., can affect recovery and thermal stability. It may be used to study PMI′s effect on various alginate biosynthetic enzymes such as phosphomannomutase (PMM), GDP-mannose pyrophosphorylase (GMP), and GDP-mannose dehydrogenase (GMD).
Biochem/physiol Actions
Phosphomannose Isomerase (PMI) catalyses the interconversion of mannose 6-phosphate (Man-6-P) and fructose 6-phosphate (Fru-6-P), which provides a link between glucose metabolism and mannosylation.
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.
Physical form
Supplied as a suspension in 3.2 M ammonium sulfate
Other Notes
One unit will convert 1.0 μmole of D-mannose 6-phosphate to D-fructose 6-phosphate per min at pH 7.6 at 25 °C, using a coupled enzyme system with phosphoglucose isomerase and glucose-6-phosphate dehydrogenase.
