Compound as reactive (4)

H⁺ + GDP + α-D-mannose 1-phosphate → GDP-α-D-mannose + phosphate

α-D-mannose 1-phosphate → mannose α-1,4-cyclic phosphate

α-D-mannose 1-phosphate + GDP-β-L-galactose → GDP-α-D-mannose + β-L-galactose 1-phosphate

H⁺ + GTP + α-D-mannose 1-phosphate → GDP-α-D-mannose + diphosphate

Compound as product (2)

a (1→4)-β-D-mannooligosaccharide + phosphate → a (1→4)-β-D-mannooligosaccharide + α-D-mannose 1-phosphate

GDP-α-D-mannose + H₂O → 2 H⁺ + GMP + α-D-mannose 1-phosphate

Reversible reaction (3)

α-D-mannose 1-phosphate ↔ α-D-mannopyranose 6-phosphate

4-O-β-D-mannopyranosyl-N-acetyl-D-glucosamine + phosphate ↔ N-acetyl-β-D-glucosamine + α-D-mannose 1-phosphate

β-1,2-D-mannobiose + phosphate ↔ D-mannopyranose + α-D-mannose 1-phosphate
