EC Tree
     3 Hydrolases
         3.1 Acting on ester bonds
             3.1.3 Phosphoric-monoester hydrolases
                3.1.3.16 protein-serine/threonine phosphatase
IUBMB Comments
A group of enzymes removing the serine- or threonine-bound phosphate group from a wide range of phosphoproteins, including a number of enzymes that have been phosphorylated under the action of a kinase (cf. EC 3.1.3.48 protein-tyrosine-phosphatase). The spleen enzyme also acts on phenolic phosphates and phosphamides (cf. EC 3.9.1.1, phosphoamidase).
