Enzyme Information

3.1.3.64
Phosphatidylinositol-3-phosphatase.
based on mapping to UniProt Q13614
1-phosphatidyl-1D-myo-inositol 3-phosphate + H(2)O = 1-phosphatidyl- 1D-myo-inositol + phosphate.
-!- This enzyme still works when the 2,3-bis(acyloxy)propyl group is removed, i.e., it hydrolyzes Ins(1,3)P(2) to Ins-1-P. -!- Formerly EC 3.1.3.65.
3.1.3.95
Phosphatidylinositol-3,5-bisphosphate 3-phosphatase.
based on mapping to UniProt Q13614
1-phosphatidyl-1D-myo-inositol 3,5-bisphosphate + H(2)O = 1-phosphatidyl- 1D-myo-inositol 5-phosphate + phosphate.
-!- The enzyme is found in both plants and animals. -!- It also has the activity of EC 3.1.3.64.
