Like the yeast enzyme, mammalian, plant and fly orthologs share the capacity for the conversion of Ins(1,4,5)P3 to Ins(1,3,4,5,6)P5. Plant and fly IPMKs recapitulate the yeast enzyme's preference for D6-hydroxyl phoshorylation followed by D3-hydroxylphosphorylation, mammalian IPMKs appear to prefer the reverse order.
