CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(R)-pantoate + ATP + beta-alanine = (R)-pantothenate + AMP +
CC         diphosphate + H(+); Xref=Rhea:RHEA:10912, ChEBI:CHEBI:15378,

CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       pH dependence:
CC         Optimum pH is 7.8. Activity decreases sharply with increasing acidity
CC         and is null at pH 7. There is only a slight decrease toward higher
CC         pH.;
CC   -!- PATHWAY: Cofactor biosynthesis; (R)-pantothenate biosynthesis; (R)-
CC       pantothenate from (R)-pantoate and beta-alanine: step 1/1.
CC   -!- SUBUNIT: Homodimer. {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- TISSUE SPECIFICITY: Expressed at low levels in leaf and root.
CC       {ECO:0000269|PubMed:10417331}.
CC   -!- SIMILARITY: Belongs to the pantothenate synthetase family.
CC       {ECO:0000305}.
