General Information
Term diphosphoinositol pentakisphosphate kinase activity ID (Ontology) GO:0000829 (Gene Ontology)
Definition Catalysis of the reaction: ATP + diphospho-1D-myo-inositol-pentakisphosphate = ADP + bis(diphospho)-1D-myo-inositol-tetrakisphosphate. The isomeric configurations of the diphospho-1D-myo-inositol-pentakisphosphate (PP-IP5) and bis(diphospho)-1D-myo-inositol-tetrakisphosphate (bis-PP-IP4) are unknown.[ PubMed:16429326 ]
Also Known As "inositol heptakisphosphate kinase activity" ; "PP-IP5 kinase activity"
