Gdp-l-galactose phosphorylase is a histidine trimer (HIT) enzyme involved in the Smirnoff Wheeler pathway of plant ascorbic acid synthesis. It is encoded by the VTC2 gene. This enzyme catalyzes the conversion of GDP-L-galactose to L-galactose 1-phosphate, consuming inorganic phosphate and producing GDP.
