| Sysname |
CDP-1L-myo-inositol:1L-myo-inositol 1-phosphate myo-inositolphosphotransferase
|
| Reaction(IUBMB) |
CDP-1L-myo-inositol + 1L-myo-inositol 1-phosphate = CMP + bis(1L-myo-inositol) 3,1'-phosphate 1-phosphate [RN: R09670]
|
| Reaction(KEGG) |
|
| Substrate |
CDP-1L-myo-inositol [CPD: C19794];
1L-myo-inositol 1-phosphate [CPD: C04006]
|
| Product |
CMP [CPD: C00055];
bis(1L-myo-inositol) 3,1'-phosphate 1-phosphate
|
| Comment |
In many organisms this activity is catalysed by a bifunctional enzyme. The di-myo-inositol-1,3'-phosphate-1'-phosphate synthase domain of the bifunctional EC 2.7.7.74/EC 2.7.8.34 (CTP:inositol-1-phosphate cytidylyltransferase/CDP-inositol:inositol-1-phosphate transferase) uses only 1L-myo-inositol 1-phosphate as an alcohol acceptor, but CDP-glycerol, as well as CDP-1L-myo-inositol and CDP-D-myo-inositol, are recognized as alcohol donors. The enzyme is involved in biosynthesis of bis(1L-myo-inositol) 1,3-phosphate, a widespread organic solute in microorganisms adapted to hot environments.
