4-phosphopantoate—beta-alanine ligase

4-Phosphopantoate—β-alanine ligase (, phosphopantothenate synthetase, TK1686 protein) is an enzyme with systematic name (R)-4-phosphopantoate:beta-alanine ligase (AMP-forming). This enzyme catalyses the following chemical reaction


 * ATP + (R)-4-phosphopantoate + β-alanine $$\rightleftharpoons$$ 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.
