The enzyme phosphopantothenoylcysteine decarboxylase (EC 4.1.1.36) catalyzes the chemical reaction
- N-[(R)-4'-phosphopantothenoyl]-L-cysteine [math]\displaystyle{ \rightleftharpoons }[/math] pantotheine 4'-phosphate + CO2
This enzyme belongs to the family of lyases, to be specific the carboxy-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is N-[(R)-4'-phosphopantothenoyl]-L-cysteine carboxy-lyase (pantotheine-4'-phosphate-forming). This enzyme participates in coenzyme A (CoA) biosynthesis from pantothenic acid.
Structural studies
As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes 1MVL, 1MVN, and 1QZU.
