General annotation (Comments)

Function	Catalyzes the condensation of pantoate with beta-alanine in an ATP-dependent reaction via a pantoyl-adenylate intermediate By similarity.
Catalytic activity	ATP + (R)-pantoate + beta-alanine = AMP + diphosphate + (R)-pantothenate.
Pathway	Cofactor biosynthesis; pantothenate biosynthesis; pantothenate from beta-alanine and pantoate: step 1/1.
Subunit structure	Homodimer By similarity.
Subcellular location	CytoplasmPotential.
Miscellaneous	The reaction proceeds by a bi uni uni bi ping pong mechanism By similarity.
Sequence similarities	Belongs to the pantothenate synthetase family.
