General annotation (Comments)

Function	Catalyzes the phosphorylation of pantothenate (Pan), the first step in CoA biosynthesis. Can not utilize a phosphoryl donor other than ATP. Ref.1 Ref.5
Catalytic activity	ATP + (R)-pantothenate = ADP + (R)-4'-phosphopantothenate. HAMAP MF_01274
Cofactor	Monovalent cations. Ammonium or potassium. Ref.5
Enzyme regulation	Not regulated by feedback inhibition by CoA and its thioesters as described for many other pantothenate kinases. Not inhibited by N-pentylpantothenamide (N5-Pan), and this compound can not act as a substrate either. Ref.1
Pathway	Cofactor biosynthesis; coenzyme A biosynthesis; CoA from (R)-pantothenate: step 1/5. HAMAP MF_01274
Subunit structure	Homodimer By similarity.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the type III pantothenate kinase family.
Biophysicochemical properties	Kinetic parameters: KM=168 µM for pantothenate Ref.1 KM=3.0 mM for ATP
Sequence caution	The sequence BAA05305.1 differs from that shown. Reason: Frameshift at position 214.
