| Reaction catalysed |
|---|
| ATP + 1D-myo-inositol 1,3,4,5,6-pentakisphosphate <=> ADP + 1D-myo-inositol hexakisphosphate |
| Comment(s) |
|---|
- The enzyme can also use Ins(1,4,5,6)P(4) and Ins(1,4,5)P(3) as
substrate.
- Inositol hexakisphosphate (phytate) accumulates in storage protein
bodies during seed development and, when hydrolyzed, releases stored
nutrients to the developing seedling before the plant is capable of
absorbing nutrients from its environment.
