Application

β-Phosphoglucomutase is used to study starch and sucrose metabolism[1]. It is used for the determination of α-amylase in clinical analysis. It is used to study galactose utilization[2] and generalized glycogenosis (Pompe′s Disease)[3].

Biochem/physiol Actions

β-Phosphoglucomutase enzymatically converts β-D-glucose 1-phosphate to β-D-glucose 6-phosphate. It is involved in starch and sucrose metabolism[1].
Enzymatically converts β-D-glucose-1-phosphate to β-D-glucose-6-phosphate.

Unit Definition

One unit is defined as the amount of enzyme which converts 1μmol of β-D-glucose-1-phosphate to β-D-glucose-6-phosphate per minute at 37°C and pH 7.0.

Other Notes

Contains EDTA and lactose.

Over the last 20 years cryocrystallography has revolutionized the field of macromolecular crystallography, greatly reducing radiation damage and allowing the collection of complete data sets at synchrotron sources. However, in order to cool crystals to 100 K cryoprotective agents must usually

Activated Lactococcus lactis beta-phosphoglucomutase (betaPGM) catalyzes the conversion of beta-d-glucose 1-phosphate (betaG1P) derived from maltose to beta-d-glucose 6-phosphate (G6P). Activation requires Mg(2+) binding and phosphorylation of the active site residue Asp8. Initial velocity techniques were used to define the steady-state

Experimental observations of fluoromagnesate and fluoroaluminate complexes of β-phosphoglucomutase (β-PGM) have demonstrated the importance of charge balance in transition-state stabilization for phosphoryl transfer enzymes. Here, direct observations of ground-state analog complexes of β-PGM involving trifluoroberyllate establish that when the geometry

To study the influence of phosphoglucomutase (PGM) activity on exopolysaccharide (EPS) synthesis in glucose- and lactose-growing Streptococcus thermophilus, a knockout PGM mutant and a strain with elevated PGM activity were constructed. The pgmA gene, encoding PGM in S. thermophilus LY03

Questions

  1. Hello, I received the enzyme pgmB (P4109) and wondered in what buffer should I dissolve the enzyme powder. Thank you

    1. This product may be reconstituted in 10 mM Potassium Phosphate, pH 7 at 5mg/mL. The stock solution is expected to be stabe for at least 1 week when stored refrigerated. For assay purposes, the enzyme is prepared just prior to use with ice cold 10 mM Potassium Phosphate, pH 7 solution duluted to 1.0 - 3.0 U/mL.
