General description
Phosphoglucomutase-1 (PGM1) is an evolutionarily conserved enzyme that belongs to the phosphohexose mutase family. It is the major isoform of PGM in skeletal muscle and most other tissues. The PGM1 gene is mapped to human chromosome 1p31.3.
Biochem/physiol Actions
Phosphoglucomutase-1 (PGM1) catalyzes the bidirectional interconversion of glucose-1-phosphate (G-1-P) and glucose-6-phosphate (G-6-P). It regulates carbohydrate metabolism, energy production, and protein N-glycosylation. PGM1 participates in the biosynthesis of nucleotide sugars required for glycan biosynthesis. Variation in the PGM1 gene leads to PGM1 deficiency, which is considered an inherited metabolic disorder in humans. PGM1 deficiency causes autosomal recessive diseases such as glycogen storage disease type XIV and congenital disorder of protein N-glycosylation. Affected patients show multiple disease phenotypes, reflecting the central role of the enzyme in glucose homeostasis. The influence of PGM1 deficiency on protein glycosylation patterns is also widespread. PGM1 acts as a metabolic tumor suppressor.

Glycogen metabolism commonly altered in cancer is just beginning to be understood. Phosphoglucomutase 1 (PGM1), the first enzyme in glycogenesis that catalyzes the reversible conversion between glucose 1-phosphate (G-1-P) and glucose 6-phosphate (G-6-P), participates in both the breakdown and synthesis

We recently redefined phosphoglucomutase-1 deficiency not only as an enzyme defect, involved in normal glycogen metabolism, but also an inborn error of protein glycosylation. Phosphoglucomutase-1 is a key enzyme in glycolysis and glycogenesis by catalyzing in the bidirectional transfer of

Human phosphoglucomutase 1 (PGM1) is an evolutionary conserved enzyme that belongs to the ubiquitous and ancient α-D-phosphohexomutases, a large enzyme superfamily with members in all three domains of life. PGM1 catalyzes the bi-directional interconversion between α-D-glucose 1-phosphate (G1P) and α-D-glucose

Phosphoglucomutase 1 deficiency is a congenital disorder of glycosylation (CDG) with multiorgan involvement affecting carbohydrate metabolism, N-glycosylation and energy production. The metabolic management consists of dietary D-galactose supplementation that ameliorates hypoglycemia, hepatic dysfunction, endocrine anomalies and growth delay. Previous studies
