IntEnz Enzyme Nomenclature


Accepted name:
GDP-D-glucose phosphorylase
Systematic name:
GDP:α-D-glucose 1-phosphate guanylyltransferase



The enzyme may be involved in prevention of misincorporation of glucose in place of mannose residues into glycoconjugates i.e. to remove accidentally produced GDP-α-D-glucose. Activities with GDP-L-galactose, GDP-D-mannose and UDP-D-glucose are all less than 3% that with GDP-D-glucose.
