| Comments |
This enzyme also phosphorylates Ins(1,3,4)P3?on O-5 and O-6. The phosphotransfer from ATP to either inositol 1,3,4-trisphosphate or inositol 3,4,5,6-tetrakisphosphate appears to be freely reversible to the extent that the enzyme can act like an inositol polyphosphate phosphatase in the presence of ADP. It can also catalyse an isomerization between Ins(1,3,4,5)P4?and Ins(1,3,4,6)P4?in the presence of ADP. |
| Reactions |
Atp + 1D-myo-inositol 3,4,5,6-tetrakisphosphate = adp + 1D-myo-inositol 1,3,4,5,6-pentakisphosphate. |
