Compound as reactive (4)

GDP-α-D-glucose → GDP-α-D-mannose

GDP-α-D-glucose + 3-phospho-D-glycerate → H⁺ + 2-O-(α-D-glucopyranosyl)-3-phospho-D-glycerate + GDP

GDP-α-D-glucose + α-D-glucose 6-phosphate → H⁺ + α,α-trehalose 6-phosphate + GDP

GDP-α-D-glucose + H₂O → H⁺ + β-D-glucopyranose + GDP

Compound as product (2)

H⁺ + GTP + α-D-glucopyranose 1-phosphate → GDP-α-D-glucose + diphosphate

α-D-glucopyranose 1-phosphate + GDP-β-L-galactose → GDP-α-D-glucose + β-L-galactose 1-phosphate

Reversible reaction (2)

GDP-α-D-glucose + (R)-glycerate ↔ H⁺ + 2-O-(α-D-glucopyranosyl)-D-glycerate + GDP

GDP-α-D-glucose + phosphate ↔ H⁺ + GDP + α-D-glucopyranose 1-phosphate
