Phosphopantothenoylcysteine decarboxylase (PPC-DC) is the enzyme that the elimination of carbon dioxide from Phosphopantothenoyl-cysteine catalysed . This is the third reaction step in the biosynthesis of coenzyme A , which takes place in most living things.

Catalyzed reaction

PPCS    4P-Pantethein+ CO 2

(R) -4'-phosphopantothenoyl-L-cysteine ​​is decarboxylated to form 4'-phosphopantethenine . The enzyme binds one molecule of FMN per subunit as a cofactor . So it is a flavoprotein .
