Proposed pathways for the synthesis of DIP, DGP, and GPI in A. fulgidus. Enzymes: 1, l-myo-inositol-1-P synthase; 2, CTP:glycerol-3-P cytidylyltransferase; 3, CTP:l-myo-inositol-1-P cytidylyltransferase; 4, DGPP synthase; 5, GPIP synthase; 6, DIPP synthase; 7, DGPP phosphatase; 8, GPIP phosphatase; and 9, DIPP phosphatase. Glc-6-P, glucose 6-phosphate; l-Ins-1-P, l-myo-inositol 1-phosphate; gly, glycerol; Ins, myo-inositol; and l-gly-3-P, l-glycerol 3-phosphate. The stereochemical configuration of the compounds has not been established.
