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;

CC Note=Binds 1 FMN per subunit. {ECO:0000255|HAMAP-Rule:MF_02225};
CC -!- PATHWAY: Cofactor biosynthesis; coenzyme A biosynthesis; CoA from (R)-
CC pantothenate: step 2/5. {ECO:0000255|HAMAP-Rule:MF_02225}.
CC -!- PATHWAY: Cofactor biosynthesis; coenzyme A biosynthesis; CoA from (R)-
CC pantothenate: step 3/5. {ECO:0000255|HAMAP-Rule:MF_02225}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the HFCD (homo-
CC oligomeric flavin containing Cys decarboxylase) superfamily.
