CC   -!- FUNCTION: Key enzyme in myo-inositol biosynthesis pathway that
CC       catalyzes the conversion of glucose 6-phosphate to 1-myo-inositol
CC       1-phosphate in a NAD-dependent manner. Rate-limiting enzyme in the
CC       synthesis of all inositol-containing compounds (By similarity).
CC   -!- CATALYTIC ACTIVITY: D-glucose 6-phosphate = 1D-myo-inositol 3-
CC       phosphate.
CC   -!- COFACTOR: NAD (By similarity).
CC   -!- PATHWAY: Polyol metabolism; myo-inositol biosynthesis; myo-
CC       inositol from D-glucose 6-phosphate: step 1/2.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity).
CC   -!- SIMILARITY: Belongs to the myo-inositol-1-phosphate synthase
CC       family.
