متن کاملPantothenate kinase-associated neurodegeneration
Disease summary: Pantothenate kinase-associated neurodegeneration (PKAN) is a rare autosomal recessive disorder that was first described by the neuropathologist Julius Hallervorden and the neurologist Hugo Spatz in 1922 [1]. The active involvement of Hallervorden in euthanasia in Germany during World War II and the discovery of the defective gene (mutation in pantothenate kinase 2 gene, located...
متن کاملPantothenate - kinase associated neurodegeneration.
Neurodegeneration with brain iron accumulation is a group of disorders, the commonest of which is PKAN (Pantothenate kinase associated neurodegeneration). We present here, a case of 18 year old boy with progressive dementia, pyramidal and extrapyramidal involvement, dysarthria, seizures and myoclonus. The patient was diagnosed as PKAN (formerly Hallervorden Spatz disease) after "eye of tiger" a...
متن کاملPantothenate biosynthesis in higher plants.
Pantothenate (vitamin B5) is a water-soluble vitamin essential for the synthesis of CoA and ACP (acyl-carrier protein, cofactors in energy yielding reactions including carbohydrate metabolism and fatty acid synthesis. Pantothenate is synthesized de novo by plants and micro-organisms; however, animals obtain the vitamin through their diet. Utilizing our knowledge of the pathway in Escherichia co...
متن کاملCompartmentalization of Mammalian Pantothenate Kinases
The pantothenate kinases (PanK) catalyze the first and the rate-limiting step in coenzyme A (CoA) biosynthesis and regulate the amount of CoA in tissues by differential isoform expression and allosteric interaction with metabolic ligands. The four human and mouse PanK proteins share a homologous carboxy-terminal catalytic domain, but differ in their amino-termini. These unique termini direct th...
