Superfamily 3.30.70.330
Functional Family Synaptojanin-1 isoform 1

Enzyme Information

3.1.3.36
Phosphoinositide 5-phosphatase.
based on mapping to UniProt O43426
1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate + H(2)O = 1-phosphatidyl- 1D-myo-inositol 4-phosphate + phosphate.
-!- These enzymes can also remove the 5-phosphate from Ins(1,4,5)P(3) and/or Ins(1,3,4,5)P(4). -!- They are a diverse family of enzymes, with differing abilities to catalyze two or more of the four reactions listed. -!- They are thought to use inositol lipids rather than inositol phosphates as substrates in vivo. -!- All of them can use either or both of PtdIns(4,5)P(2) and PtdIns(3,4,5)P(3) as substrates; this is the main property that distinguishes them from EC 3.1.3.56.
