GDP-L-galactose phosphorylase

FieldValue
NameGDP-L-galactose phosphorylase
EC_number2.7.7.69

GDP-L-galactose phosphorylase (, VTC2, VTC5) is an enzyme with systematic name GDP:alpha-L-galactose 1-phosphate guanylyltransferase. This enzyme catalyses the following chemical reaction

: GDP-L-galactose + phosphate \rightleftharpoons alpha-L-galactose 1-phosphate + GDP

The enzyme catalyses a reaction of the Smirnoff-Wheeler pathway.
