Acting on ester bonds;
Phosphoric-monoester hydrolases
BRITE hierarchy
Sysname
beta-L-galactose-1-phosphate phosphohydrolase
Reaction(IUBMB)
beta-L-galactose 1-phosphate + H2O = L-galactose + phosphate [RN:R07674]
Reaction(KEGG)
Substrate
beta-L-galactose 1-phosphate [CPD:C15926];
H2O [CPD:C00001]
Product
L-galactose [CPD:C01825];
phosphate [CPD:C00009]
Comment
The enzyme from plants also has the activity of EC 3.1.3.25, inositol-phosphate phosphatase. The enzymes have very low activity with D-galactose 1-phosphate (cf. EC 3.1.3.94, D-galactose 1-phosphate phosphatase).
