Pantothenate kinase regulation of the intracellular concentration of coenzyme A.
Pantothenate kinase (PanK) is the key regulatory enzyme in the CoA biosynthetic pathway in bacteria and is thought to play a similar role in mammalian cells. We examined this hypothesis by identifying and characterizing two murine cDNAs that encoded PanK. The two cDNAs were predicted to arise from alternate splicing of the same gene to yield different mRNAs that encode two isoforms (mPanK1alpha...

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 کاملActivation of human mitochondrial pantothenate kinase 2 by palmitoylcarnitine.
The human isoform 2 of pantothenate kinase (PanK2) is localized to the mitochondria, and mutations in this protein are associated with a progressive neurodegenerative disorder. PanK2 inhibition by acetyl-CoA is so stringent (IC50 < 1 microM) that it is unclear how the enzyme functions in the presence of intracellular CoA concentrations. Palmitoylcarnitine was discovered to be a potent activator...
