Function | Catalyzes the phosphorylation of pantothenate (Pan), the first step in CoA biosynthesis. |
Catalytic activity | RHEA:16373: (R)-pantothenate + ATP = (R)-4'-phosphopantothenate + ADP + H(+)
EC 2.7.1.33 |
Cofactor | NH4(+) K(+) Note: A monovalent cation. Ammonium or potassium. |
Pathway | Cofactor biosynthesis; coenzyme A biosynthesis; CoA from (R)-pantothenate: step 1/5. |
Subunit | Homodimer. |
Subcellular location | Cytoplasm. |
Similarity | Belongs to the type III pantothenate kinase family. |
