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}.
CC -!- FUNCTION: Catalyzes two steps in the biosynthesis of coenzyme A. In the
