This family of archaeal proteins includes pantothenate synthetase from Methanosarcina mazei and 4-phosphopantoate--beta-alanine ligase (phosphopantothenate synthetase) from Pyrococcus kodakaraensis. Pantothenate synthetase catalyses the condensation of pantoate with beta-alanine in an ATP-dependent and ADP-producing reaction [1]. 4-phosphopantoate--beta-alanine ligase catalyses the conversion of (R)-4-phosphopantoate and beta-alanine to 4'-phosphopantothenate in the CoA biosynthesis pathway. It cannot use (R)-pantoate as substrate and thus does not display pantothenate synthetase activity [2].	Domain
