The α- and β-phosphoglucomutases are enzymes found in all plant and animal cells that catalyze the reversible isomerization of glucose-1-phosphate (G1P) and glucose-6-phosphate (G6P) (Scheme 5).

What is phosphoglucomutase used in?

Introduction. Phosphoglucomutase (PGM) (EC 5.4. 2.21) is an evolutionarily conserved and well characterized enzyme that catalyzes the interconversion of glucose 1-phosphate and glucose 6-phosphate via a glucose 1,6-diphosphate intermediate, making it a key enzyme in both glycolysis and gluconeogenesis.

Is phosphoglucomutase in glycolysis?

Phosphoglucomutase-1 is a key enzyme in glycolysis and glycogenesis by catalyzing in the bidirectional transfer of phosphate from position 1 to 6 on glucose. Glucose-1-P and UDP-glucose are closely linked to galactose metabolism. Normal PGM1 activity is important for effective glycolysis during fasting.
