A protein complex that catalyzes decarboxylation of 4'-phosphopantothenoylcysteine to yield 4'-phosphopantetheine; this is the third step in the biosynthesis of Coenzyme A. The complex is homotrimeric in many eukaryotes, but is a heterotrimer in Saccharomyces. [ http://www.ncbi.nlm.nih.gov/pubmed/19915539 ]
