Transferring phosphorus-containing groups;
Nucleotidyltransferases
BRITE hierarchy
Sysname
GDP:alpha-D-glucose 1-phosphate guanylyltransferase
Reaction(IUBMB)
GDP-alpha-D-glucose + phosphate = alpha-D-glucose 1-phosphate + GDP [RN:
R09752 ]
Reaction(KEGG)
Substrate
Product
Comment
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-alpha-D-glucose. Activities with GDP-L-galactose, GDP-D-mannose and UDP-D-glucose are all less than 3% that with GDP-D-glucose.
