CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01274};
CC       Note=A monovalent cation. Ammonium or potassium. {ECO:0000255|HAMAP-
CC       Rule:MF_01274};
CC   -!- PATHWAY: Cofactor biosynthesis; coenzyme A biosynthesis; CoA from (R)-
CC       pantothenate: step 1/5. {ECO:0000255|HAMAP-Rule:MF_01274}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01274}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01274}.
CC   -!- SIMILARITY: Belongs to the type III pantothenate kinase family.
