B	phosphoglucomutase M-CSA #352	Phosphoglucomutase catalyses the transfer of a phosphate fragment between the 1- and 6-O atoms of glucose. As suggested by the enzyme's name, in its stable form it exists esterified, at the gamma-hydroxyl group of Ser116. The enzyme is involved in the glycogenolysis pathway. Once a 1-phosphate glucose molecule is released from glycogen by glycogen phosphorylase, phosphoglucomutase catalyses the interconversion of this relatively useless metabolic intermediate into 6-phosphate glucose. This metabolite can then be utilised in multiple cellular pathways including the glycolytic, pentose phosphate or biosynthetic pathways. When glucose levels are high, phosphoglucomutase can act in the opposite fashion, converting 6-phosphate glucose to 1-phosphate glucose. In combination with UDP-glucose-pyrophosphorylase and glycogen synthase, this change in equilibrium will result in the reformation of the 1-phosphate glucose monomer with a glycogen polymer.
