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,
