CC Evidence={ECO:0000255|HAMAP-Rule:MF_01274};
CC Name=K(+); Xref=ChEBI:CHEBI:29103;
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.
CC {ECO:0000255|HAMAP-Rule:MF_01274}.
