spinqualitylabelsall models Pantothenate kinase III dimer complex with pantothenate, glycerol and ethane diol, 2f9w Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image 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 [3]. .
