Bacteriol. 187:4992-4999(2005). 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 -!- CATALYTIC ACTIVITY: CC Reaction=(R)-4'-phosphopantothenate + CTP + L-cysteine = CMP + CC diphosphate + H(+) + N-[(R)-4-phosphopantothenoyl]-L-cysteine; CC Xref=Rhea:RHEA:19397, ChEBI:CHEBI:10986, ChEBI:CHEBI:15378, CC ChEBI:CHEBI:33019, ChEBI:CHEBI:35235, ChEBI:CHEBI:37563, CC ChEBI:CHEBI:59458, ChEBI:CHEBI:60377; EC=6.3.2.5; CC Evidence={ECO:0000256|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 ChEBI:CHEBI:16526, ChEBI:CHEBI:59458, ChEBI:CHEBI:61723; EC=4.1.1.36; CC Evidence={ECO:0000256|HAMAP-Rule:MF_02225}; CC -!- COFACTOR: CC Name=FMN; Xref=ChEBI:CHEBI:58210; CC Evidence={ECO:0000256|HAMAP-Rule:MF_02225}; CC Note=Binds 1 FMN per subunit. {ECO:0000256|HAMAP-Rule:MF_02225}; CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; CC Evidence={ECO:0000256|HAMAP-Rule:MF_02225}; CC -!- PATHWAY: Cofactor biosynthesis; coenzyme A biosynthesis. CC {ECO:0000256|HAMAP-Rule:MF_02225}. CC -!- SIMILARITY: In the C-terminal section; belongs to the PPC synthetase CC family. {ECO:0000256|HAMAP-Rule:MF_02225}. CC -!- SIMILARITY: In the N-terminal section; belongs to the HFCD (homo- CC oligomeric flavin containing Cys decarboxylase) superfamily. CC {ECO:0000256|HAMAP-Rule:MF_02225}.
