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 18.104.22.168, inositol-phosphate phosphatase. The enzyme has very low activity with L-galactose 1-phosphate (cf. EC 22.214.171.124, L-galactose 1-phosphate phosphatase).
