Chains	Enzyme Name	Description	Catalytic Residues
A	pantoate-beta-alanine ligase M-CSA #229	Pantothenate synthetase (PS), isolated from Mycobacterium tuberculosis, catalyses the ATP-dependent condensation between pantoate and beta-alanine to form pantothenate. This is the last step in the biosynthesis of pantothenate, which is required for CoA synthesis. The reaction proceeds by a Bi Uni Uni Bi Ping Pong kinetic mechanism. PS is a potential drug target for the treatment of tuberculosis.
