Function
function
Catalyzes two sequential steps in the biosynthesis of coenzyme A. In the first step cysteine is conjugated to 4'-phosphopantothenate to form 4-phosphopantothenoylcysteine. In the second step the latter compound is decarboxylated to form 4'-phosphopantotheine.

Catalytic activity
- (R)-4'-phosphopantothenate + L-cysteine + CTP = N-[(R)-4-phosphopantothenoyl]-L-cysteine + CMP + diphosphate + H+
Cofactor
Protein has several cofactor binding sites:
Note: Binds 1 FMN per subunit.
Pathway
Cofactor biosynthesis; coenzyme A biosynthesis; CoA from (R)-pantothenate: step 2/5.
Cofactor biosynthesis; coenzyme A biosynthesis; CoA from (R)-pantothenate: step 3/5.
