Phosphoglucomutase

UniProtKB accession:  Q4WY53

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the reversible isomerization of alpha-D-glucose 1-phosphate to alpha-D-glucose 6-phosphate (By similarity). The mechanism proceeds via the intermediate compound alpha-D-glucose 1,6-bisphosphate (By similarity). Key enzyme in hexose metabolism (By similarity). The reverse reaction is an essential step for biosynthesis because glucose 1-phosphate is the starting point for the synthesis of UDP-glucose, which acts as a precursor for the synthesis of oligosaccharides and trehalose (By similarity).
