CC -!- FUNCTION: Catalyzes the condensation of pantoate with beta-alanine in
CC an ATP-dependent reaction via a pantoyl-adenylate intermediate.
CC {ECO:0000255|HAMAP-Rule:MF_01349}.
CC -!- FUNCTION: Catalyzes the transfer of a phosphate group from ATP to
CC either CMP or dCMP to form CDP or dCDP and ADP, respectively.
CC {ECO:0000255|HAMAP-Rule:MF_01349}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(R)-pantoate + ATP + beta-alanine = (R)-pantothenate + AMP +
CC diphosphate + H(+); Xref=Rhea:RHEA:10912, ChEBI:CHEBI:15378,

CC ChEBI:CHEBI:456216; EC=2.7.4.25; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01349};
CC -!- PATHWAY: Cofactor biosynthesis; (R)-pantothenate biosynthesis; (R)-
CC pantothenate from (R)-pantoate and beta-alanine: step 1/1.
CC {ECO:0000255|HAMAP-Rule:MF_01349}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01349}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the pantothenate
CC synthetase family. {ECO:0000255|HAMAP-Rule:MF_01349}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the cytidylate kinase
CC family. Type 1 subfamily. {ECO:0000255|HAMAP-Rule:MF_01349}.
