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.

Plant resistance (R) genes are highly effective in protecting plants against diseases, but pathogens can overcome such genes relatively easily by adaptation. Consequently, in many cases R genes do not confer durable resistance in agricultural environments. One possible strategy to

The specific activities of phosphomannose isomerase (PMI), phosphomannomutase (PMM), GDP-mannose pyrophosphorylase (GMP), and GDP-mannose dehydrogenase (GMD) were compared in a mucoid cystic fibrosis isolate of Pseudomonas aeruginosa and in two spontaneous nonmucoid revertants. In both revertants some or all of

Mannose-6-phosphate isomerase catalyzes the interconversion of mannose-6-phosphate and fructose-6-phosphate. The gene encoding a putative mannose-6-phosphate isomerase from Thermus thermophilus was cloned and expressed in Escherichia coli. The native enzyme was a 29 kDa monomer with activity maxima for mannose 6-phosphate at

Phosphomannose isomerase (PMI) catalyzes the reversible interconversion of fructose 6-phosphate (Fru-6-P) and mannose 6-phosphate (Man-6-P), providing a link between glycolysis and the mannose metabolic pathway. In this study, we identified pmi gene (Mapmi) from the entomopathogenic fungus, Metarhizium acridum, and

Phosphomannose isomerases (PMIs) in bacteria and fungi catalyze the reversible conversion of D-fructose-6-phosphate to D-mannose-6-phosphate during biosynthesis of GDP-mannose, which is the main intermediate in the mannosylation of important cell wall components, glycoproteins, and certain glycolipids. In the present study
