1-phosphatidyl-1D-myo-inositol-3,4-bisphosphate 4-phosphohydrolase
1-phosphatidyl-myo-inositol 3,4-bisphosphate + H2O = 1-phosphatidyl-1D-myo-inositol 3-phosphate + phosphate [RN:R07299]
(other) R04372 R10950
1-phosphatidyl-myo-inositol 3,4-bisphosphate;
H2O [CPD:C00001]
1-phosphatidyl-1D-myo-inositol 3-phosphate [CPD:C04549];
phosphate [CPD:C00009]
Mg2+-independent. This enzyme still works when the 2,3-bis(acyloxy)propyl group is removed, i.e., it hydrolyses Ins(1,3,4)P3 to Ins(1,3)P2. It also converts Ins(3,4)P2 into Ins-3-P.
