ID 6.3.2.44 DE pantoate--beta-alanine ligase (ADP-forming). AN pantoate--beta-alanine ligase. AN pantothenate synthetase. CA (R)-pantoate + ATP + beta-alanine = (R)-pantothenate + ADP + H(+) + CA phosphate. CC -!- The enzyme, characterized from the archaeon Methanosarcina mazei, CC is involved in the biosynthesis of pantothenate. CC -!- It is different from EC 6.3.2.1, the AMP-forming pantoate-beta- CC alanine ligase found in bacteria and eukaryota. CC -!- Formerly EC 6.3.2.n5. //
