BRITE hierarchy
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].
