Function

Pantothenate kinase (PanK) phosphorylates pantothenate (vitamin B5) (PAU) to form 4’-phosphopantothenate (PPT) using ATP as phosphate source. This is the first step in coenzyme A biosynthesis[1].

Three types of PanK are known.

  • PanK I found in bacteria
  • PanK II found mostly in eukaryotes
  • PanK III found in bacteria and known as CoaX.

Disease

Mutations in PanK II cause the autosomal-recessive disorder Pantothenate kinase-associated neurodegeneration[2].

Structural highlights
