Name
1L-myo-inositol 1-phosphate cytidylyltransferase;
CTP:inositol-1-phosphate cytidylyltransferase (bifunctional CTP:inositol-1-phosphate cytidylyltransferase/CDP-inositol:inositol-1-phosphate transferase (IPCT/DIPPS));

L-myo-inositol-1-phosphate cytidylyltransferase
Class
Transferases;
Transferring phosphorus-containing groups;
Nucleotidyltransferases
Sysname
CTP:1L-myo-inositol 1-phosphate cytidylyltransferase
Reaction(IUBMB)
CTP + 1L-myo-inositol 1-phosphate = diphosphate + CDP-1L-myo-inositol [RN:R09669]
Reaction(KEGG)
R09669
Substrate
CTP [CPD:C00063];
1L-myo-inositol 1-phosphate [CPD:C04006]
Product
diphosphate [CPD:C00013];
CDP-1L-myo-inositol [CPD:C19794]
Comment
In many organisms this activity is catalysed by a bifunctional enzyme. The cytidylyltransferase 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) is absolutely specific for CTP and 1L-myo-inositol 1-phosphate. The enzyme is involved in biosynthesis of bis(1L-myo-inositol) 1,3'-phosphate, a widespread organic solute in microorganisms adapted to hot environments.
