'''4-phosphopantoate—beta-alanine ligase''' ({{EC number|6.3.2.36}}, ''phosphopantothenate synthetase'', ''TK1686 protein'') is an [[enzyme]] with system name ''(R)-4-phosphopantoate:beta-alanine ligase (AMP-forming)''.<ref>{{cite journal | title = Pantoate kinase and phosphopantothenate synthetase, two novel enzymes necessary for CoA biosynthesis in the ''Archaea'' |author = Yokooji, Y., Tomita, H., Atomi, H. and Imanaka, T. |journal = J. Biol. Chem. |year = 2009 |volume = 284 |pages = 28137–28145 |pmid = 19666462}}</ref> This enzyme [[catalysis|catalyses]] the following [[chemical reaction]]

: ATP + (R)-4-phosphopantoate + [[beta-alanine]] <math>\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.
