Catalyzes the condensation of pantoate with beta-alanine in an ATP-dependent reaction via a pantoyl-adenylate intermediate. Catalyzes the transfer of a phosphate group from ATP to either CMP or dCMP to form CDP or dCDP and ADP, respectively. (R)-pantoate + ATP + beta-alanine = (R)-pantothenate + AMP + diphosphate + H(+) ATP + CMP = ADP + CDP ATP + dCMP = ADP + dCDP Cofactor biosynthesis; (R)-pantothenate biosynthesis; (R)-pantothenate from (R)-pantoate and beta-alanine: step 1/1. In the N-terminal section; belongs to the pantothenate synthetase family. In the C-terminal section; belongs to the cytidylate kinase family. Type 1 subfamily.
