The direction shown, i.e. which substrates are on the left and right sides, is in accordance with the direction in which it was curated.

Mass balance status: Balance undetermined; a substrate lacks a chemical formula

Instance reactions:
α-D-glucopyranose 1-phosphate + H2O → D-glucopyranose + phosphate (3.1.3.10)

α-D-glucose 6-phosphate + H2O → α-D-glucopyranose + phosphate (3.1.3.9/3.1.3.58)

β-D-glucose 6-phosphate + H2O → β-D-glucopyranose + phosphate (3.1.3.9/3.1.3.58)

a hexose phosphate + H2O = a hexose + phosphate (3.1.3.-)

β-D-fructofuranose 1-phosphate + H2O → β-D-fructofuranose + phosphate (3.1.3.-)

Enzyme Commission Primary Name: sugar-phosphatase

Enzyme Commission Summary:
Has a wide specificity, acting on aldohexose 1-phosphates, ketohexose 1-phosphates, aldohexose 6-phosphates, ketohexose 6-phosphates, both phosphate ester bonds of fructose 1,6-bisphosphate, phosphoric esters of disaccharides, and on pentose and triose phosphates, but at a slower rate.
