Reaction: A phosphate monoester + H2O = an alcohol + phosphate
Other name(s): alkaline phosphomonoesterase; phosphomonoesterase; glycerophosphatase; alkaline phosphohydrolase; alkaline phenyl phosphatase; orthophosphoric-monoester phosphohydrolase (alkaline optimum)
Systematic name: phosphate-monoester phosphohydrolase (alkaline optimum)
Comments: Wide specificity. Also catalyses transphosphorylations. The human placental enzyme is a zinc protein. Some enzymes hydrolyse diphosphate (cf. EC 3.6.1.1 inorganic diphosphatase)
