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.
Unit Definition
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.

In the design of inhibitors of phosphosugar metabolizing enzymes and receptors with therapeutic interest, malonate has been reported in a number of cases as a good and hydrolytically-stable surrogate of the phosphate group, since both functions are dianionic at physiological

Clostridium thermocellum, an anaerobic, thermophilic, and ethanogenic bacterium produces a large cellulase complex termed the cellulosome and many free glycosyl hydrolases. Most cellulase genes scatter around the genome. We mapped the transcripts of the six-gene cluster celC-glyR3-licA-orf4-manB-celT and determined their

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 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
