General Information

General Information Comment Organism
evolution phylogenetic tree showing the evolutionary relatedness of GmITPK2 with ITPKs of monocot and dicot species using Entamoeba histolytica (EhITPK) as an outgroup member Glycine max
metabolism following the formation of myo-inositol-3-phosphate, sequential phosphorylation reactions via action of various inositol phosphate kinases-myo-inositol kinase (Mik), inositol 1,3,4-trisphosphate kinase (Itpk), inositol 1,4,5-trisphosphate 3/6 kinase (Ipk2), and inositol 1,3,4,5,6-pentakisphosphate kinase (Ipk1) lead to phytic acid (PA, myo-inositol 1,2,3,4,5,6-hexakisphosphate) synthesis via the lipid-independent pathway and fine-tune the phosphorous flux towards PA accumulation Glycine max
