Pathway for DIP biosynthesis using l-[1-13C]myo-inositol-1-phosphate as a labeled precursor. The asterisks highlight the positions of labeled carbon atoms in the several intermediate metabolites and end products as established in this work from 13C- and 31P-NMR analyses of reaction mixtures containing the bifunctional enzyme IPCT/DIPPS (see the text for details). Dashes are used to designate the carbon atoms in the phosphorylated inositol moiety.
