Pantothenoylcysteine decarboxylase
In enzymology, a pantothenoylcysteine decarboxylase (EC4.1.1.30) is an enzyme that catalyzes the chemical reaction
Hence, this enzyme has one substrate, N-((R)-pantothenoyl)-L-cysteine, and two products, pantetheine and CO2.
This enzyme belongs to the family of lyases, specifically the carboxy-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is N-[(R)-pantothenoyl]-L-cysteine carboxy-lyase (pantetheine-forming). Other names in common use include pantothenylcysteine decarboxylase, and N-[(R)-pantothenoyl]-L-cysteine carboxy-lyase. This enzyme participates in pantothenate and coa biosynthesis.
