IUBMB Enzyme Nomenclature


Accepted name: D-galactose 1-phosphate phosphatase

Reaction: α-D-galactose 1-phosphate + H2O = D-galactose + phosphate

Systematic name: α-D-galactose-1-phosphate phosphohydrolase

Comments: The human enzyme also has the activity of EC, inositol-phosphate phosphatase. The enzyme has very low activity with L-galactose 1-phosphate (cf. EC, L-galactose 1-phosphate phosphatase).
