2.7.1.158 | ATP + 1D-myo-inositol 1,3,4,5,6-pentakisphosphate |
cytoplasmic production of 1D-myo-inositol hexakisphosphate is sufficient for mediating the Gle1-mRNA export pathway |
2.7.1.158 | ATP + 1D-myo-inositol 1,3,4,5,6-pentakisphosphate |
it is suggested that the enzyme is necessary for yolk sac development or function. Loss of inositol 1,3,4,5,6-pentakisphosphate 2-kinase is lethal |
2.7.1.158 | ATP + 1D-myo-inositol 1,3,4,5,6-pentakisphosphate |
the enzyme may be involved in both inositol hexakisphosphate formation in maturing seeds and ATP resynthesis in germinating seeds |
2.7.1.158 | ATP + 1D-myo-inositol 1,3,4,5,6-pentakisphosphate |
the product 1D-myo-inositol hexakisphosphate plays a role in messenger RNA export |
2.7.1.158 | ATP + 1D-myo-inositol 1,3,4,5,6-pentakisphosphate |
rate-determining step in production of 1D-myo-inositol hexakisphosphate |
2.7.1.158 | ATP + 1D-myo-inositol 1,3,4,5,6-pentakisphosphate |
the predominant activity of StITPK1 is that of an InsP5-ADP phosphotransferase. |
