General annotation (Comments)

Function

Catalyzes the condensation of pantoate with beta-alanine in an ATP-dependent reaction via a pantoyl-adenylate intermediate By similarity. HAMAP-Rule MF_00158

Catalytic activity

ATP + (R)-pantoate + beta-alanine = AMP + diphosphate + (R)-pantothenate. HAMAP-Rule MF_00158

Pathway

Cofactor biosynthesis; (R)-pantothenate biosynthesis; (R)-pantothenate from (R)-pantoate and beta-alanine: step 1/1. HAMAP-Rule MF_00158

Subunit structure

Homodimer By similarity. HAMAP-Rule MF_00158

Subcellular location

Cytoplasm Potential HAMAP-Rule MF_00158.

Miscellaneous

The reaction proceeds by a bi uni uni bi ping pong mechanism By similarity.

Sequence similarities

Belongs to the pantothenate synthetase family.
