Protein attributes

Sequence length	129 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Provides activated glycerol phosphate for teichoic acid synthesis, via incorporation into both the linkage unit and the teichoic acid polymer by tagB and tagF.
Catalytic activity	CTP + sn-glycerol 3-phosphate = diphosphate + CDP-glycerol.
Cofactor	Divalent metal cations. Prefers cobalt, magnesium, manganese or iron.
Enzyme regulation	Inhibited by the divalent cations cadmium, mercury, tin, copper and zinc.
Pathway	Cell wall biogenesis; poly(glucopyranosyl N-acetylgalactosamine 1-phosphate) teichoic acid biosynthesis. Cell wall biogenesis; poly(glycerol phosphate) teichoic acid biosynthesis.
Subunit structure	Homodimer.
Subcellular location	Cytoplasm.
Induction	Positively regulated by yycF. Mainly expressed during exponential growth and rapidly shut off as cells enter the stationary phase.
Miscellaneous	Proceeds via a random order reaction mechanism where there is negative cooperativity in the binding of substrates but not in catalysis.
Sequence similarities	Belongs to the cytidylyltransferase family.
