CC   -!- FUNCTION: Catalyzes the transfer of the cytidylyl group of CTP to D-
CC       ribitol 5-phosphate. {ECO:0000255|HAMAP-Rule:MF_02068}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-ribitol 5-phosphate + CTP + H(+) = CDP-L-ribitol +
CC         diphosphate; Xref=Rhea:RHEA:12456, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:33019, ChEBI:CHEBI:37563, ChEBI:CHEBI:57608,
CC         ChEBI:CHEBI:57695; EC=2.7.7.40; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_02068};
CC   -!- PATHWAY: Cell wall biogenesis; poly(ribitol phosphate) teichoic acid
CC       biosynthesis. {ECO:0000255|HAMAP-Rule:MF_02068}.
CC   -!- SIMILARITY: Belongs to the IspD/TarI cytidylyltransferase family. TarI
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_02068}.
