ID   2.7.8.34
DE   CDP-L-myo-inositol myo-inositolphosphotransferase.
AN   DIPPS.
CA   1D-myo-inositol 3-phosphate + CDP-1L-myo-inositol = bis(1L-myo-inositol)
CA   3,1'-phosphate 1-phosphate + CMP + H(+).
CC   -!- In many organisms this activity is catalyzed by a bifunctional
CC       enzyme.
CC   -!- The di-myo-inositol-1,3'-phosphate-1'-phosphate synthase domain of
CC       the bifunctional EC 2.7.7.74/EC 2.7.8.34 uses only 1L-myo-inositol
CC       1-phosphate as an alcohol acceptor, but CDP-glycerol, as well as CDP-
CC       1L-myo-inositol and CDP-D-myo-inositol, are recognized as alcohol
CC       donors.
CC   -!- The enzyme is involved in biosynthesis of bis(1L-myo-inositol) 1,3-
CC       phosphate, a widespread organic solute in microorganisms adapted to
CC       hot environments.
