CC -!- FUNCTION: Catalyzes two sequential steps in the biosynthesis of CC coenzyme A. In the first step cysteine is conjugated to 4'- CC phosphopantothenate to form 4-phosphopantothenoylcysteine. In the CC second step the latter compound is decarboxylated to form 4'- CC phosphopantotheine. {ECO:0000256|HAMAP-Rule:MF_02225}.
