一般說明

Research area: CellSignalling. The phosphoglucomutase (PGM) molecule, a single polypeptide chain, is made up of four α/β domains. The domains form a compact heart-shaped structure with a large fissure between the two lobes, and the molecule comprises about 40 secondary structural components. The active enzymatic site of the molecule is located at the bottom of the crevice on the surface of domain I. Rabbit muscle phosphoglucomutase (RB-PGM) is a monomer with a unique four-domain architecture.

應用

Phosphoglucomutase from rabbit muscle may be used in dephosphorylation to investigate the hexose bisphosphate activation of phosphoglucomutase.

生化/生理作用

Phosphoglucomutase (PGM) mainly catalyzes the interconversion of glucose 1-phosphate and glucose 6-phosphate via a glucose 1,6-diphosphate intermediate. Hence it plays a key role in glycolysis and gluconeogenesis.

單位定義

One unit will convert 1.0 μmole of α-D-glucose 1-phosphate to α-D-glucose 6-phosphate per min at pH 7.4 at 30 °C.

The hexose bisphosphate activation of phosphoglucomutase was investigated with both plant (pea and mung bean) and animal (rabbit muscle) sources of the enzyme. Plant phosphoglucomutase was purified about 50-fold from seeds, and to a lesser extent, from seedlings of Pisum

Three-dimensional structural models of three members of the phosphoglucomutase (PGM) superfamily, parafusin, phosphoglucomutase-related protein and sarcoplasmic reticulum phosphoglucomutase, were constructed by homology modeling based on the known crystal structure of rabbit muscle phosphoglucomutase.
