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:0000255|HAMAP-Rule:MF_02225}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + N-[(R)-4-phosphopantothenoyl]-L-cysteine = (R)-4'-
CC phosphopantetheine + CO2; Xref=Rhea:RHEA:16793, ChEBI:CHEBI:15378,

CC -!- CATALYTIC ACTIVITY:
CC Reaction=(R)-4'-phosphopantothenate + CTP + L-cysteine = CMP +
CC diphosphate + H(+) + N-[(R)-4-phosphopantothenoyl]-L-cysteine;
