4-Phosphopantoate—β-alanine ligase (EC 6.3.2.36, phosphopantothenate synthetase, TK1686 protein) is an enzyme with systematic name (R)-4-phosphopantoate:beta-alanine ligase (AMP-forming).[1] This enzyme catalyses the following chemical reaction
- ATP + (R)-4-phosphopantoate + β-alanine [math]\displaystyle{ \rightleftharpoons }[/math] AMP + diphosphate + (R)-4'-phosphopantothenate
The conversion of (R)-pantoate to (R)-4'-phosphopantothenate is part of the pathway leading to biosynthesis of 4'-phosphopantetheine.
