IUBMB Enzyme Nomenclature


Accepted name: sugar-terminal-phosphatase

Reaction: D-glucose 6-phosphate + H2O = D-glucose + phosphate

Other name(s): xylitol-5-phosphatase

Systematic name: sugar-ω-phosphate phosphohydrolase

Comments: Acts on sugars and polyols phosphorylated on the terminal carbon, with a preference for sugars with a D-erythro-configuration, e.g. good substrates are glucose 6-phosphate, mannose 6-phosphate, 6-phosphogluconate, erythrose 4-phosphate and xylitol 5-phosphate.
