KEGG ENZYME: 2.7.7.74

ENZYME: 2.7.7.74

Entry

EC 2.7.7.74                 Enzyme

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));
IPCT (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.
