| Sysname |
ATP:1D-myo-inositol-5-diphosphate-pentakisphosphate phosphotransferase
|
| Reaction(IUBMB) |
ATP + 1D-myo-inositol 5-diphosphate pentakisphosphate = ADP + 1D-myo-inositol bisdiphosphate tetrakisphosphate (isomeric configuration unknown) [RN: R08964]
|
| Reaction(KEGG) |
|
| Substrate |
ATP [CPD: C00002];
1D-myo-inositol 5-diphosphate pentakisphosphate [CPD: C11526]
|
| Product |
ADP [CPD: C00008];
1D-myo-inositol bisdiphosphate tetrakisphosphate [CPD: C18058]
|
| Comment |
This enzyme is activated by osmotic shock [4]. The enzyme can also phosphorylate InsP6, but more slowly [4]. Ins(1,3,4,5,6)P5, POP-InsP4 and (POP)2-InsP3 are not substrates [4].
