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_00158}.
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:15980, ChEBI:CHEBI:29032, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:33019, ChEBI:CHEBI:57966, ChEBI:CHEBI:456215; EC=6.3.2.1;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00158};
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_00158}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00158}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00158}.
CC -!- MISCELLANEOUS: The reaction proceeds by a bi uni uni bi ping pong
CC mechanism. {ECO:0000255|HAMAP-Rule:MF_00158}.
CC -!- SIMILARITY: Belongs to the pantothenate synthetase family.
CC {ECO:0000255|HAMAP-Rule:MF_00158}.
