Enzyme Information
| 3.1.3.16 |
Protein-serine/threonine phosphatase.
based on mapping to UniProt P60484
[a protein]-serine/threonine phosphate + H(2)O = [a protein]- serine/threonine + phosphate.
-!- A group of enzymes removing the serine- or threonine-bound phosphate group from a wide range of phosphoproteins, including a number of enzymes which have been phosphorylated under the action of a kinase (cf. EC 3.1.3.48). -!- The spleen enzyme also acts on phenolic phosphates and phosphamides (cf. EC 3.9.1.1).

| 3.1.3.67 |
Phosphatidylinositol-3,4,5-trisphosphate 3-phosphatase.
based on mapping to UniProt P60484
Phosphatidylinositol 3,4,5-trisphosphate + H(2)O = phosphatidylinositol 4,5-bisphosphate + phosphate.
-!- Does not dephosphorylate inositol 4,5-bisphosphate. -!- This enzyme still works when the 2,3-bis(acyloxy)propyl group is removed, i.e., it hydrolyzes Ins(1,3,4,5)P(4) to Ins(1,4,5)P(3).
|
| 3.1.3.48 |
Protein-tyrosine-phosphatase.
based on mapping to UniProt P60484
Protein tyrosine phosphate + H(2)O = protein tyrosine + phosphate.
-!- Dephosphorylates O-phosphotyrosine groups in phosphoproteins, such as the products of EC 2.7.10.2.
