Function
function
Catalyzes the condensation of pantoate with beta-alanine in an ATP-dependent reaction via a pantoyl-adenylate intermediate.
Miscellaneous
The reaction proceeds by a bi uni uni bi ping pong mechanism.
Catalytic activity
- (R)-pantoate + beta-alanine + ATP = (R)-pantothenate + AMP + diphosphate + H+
Pathway
Cofactor biosynthesis; (R)-pantothenate biosynthesis; (R)-pantothenate from (R)-pantoate and beta-alanine: step 1/1.
