Beschreibung

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.
