Accepted name: |
GDP-D-glucose phosphorylase |
Reaction: |
GDP-α-D-glucose + phosphate = α-D-glucose 1-phosphate + GDP |
Systematic name: |
GDP:α-D-glucose 1-phosphate guanylyltransferase |
Comments: |
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. |
