Pantothenol is a provitamin of pantothenic acid (vitamin B5) that is widely used in healthcare and cosmetic products. This analog of pantothenate has been shown to markedly inhibit the phosphorylation activity of the prokaryotic type II pantothenate kinase of Staphylococcus aureus, which catalyzes the first step of the coenzyme A biosynthetic pathway. Since type II enzymes are found exclusively...
BACKGROUND Pantothenate-kinase-associated neurodegeneration (PKAN) is an autosomal recessive neurodegenerative disorder that is characterized by progressive extrapyramidal signs, visual loss, and cognitive impairment. PKAN is caused by mutations in the pantothenate kinase gene (PANK2), which is located on chromosome 20p13 and encodes pantothenate kinase, the key regulatory enzyme in coenzyme-A ...
Coenzyme A (CoA) holds a central position in cellular metabolism and therefore can be assumed to be an ancient molecule. Starting from the known E. coli and human enzymes required for the biosynthesis of CoA, phylogenetic profiles and chromosomal proximity methods enabled an almost complete reconstruction of archaeal CoA biosynthesis. This includes the identification of strong candidates for ar...
Pantothenate Kinase-Associated Neurodegeneration (PKAN) is a form of Neurodegeneration with Brain Iron Accumulation (NBIA) associated with mutations in the pantothenate kinase 2 gene (PANK2). Pantothenate kinases catalyze the rate-limiting step of coenzyme A synthesis and Pank2 is the only pantothenate kinase isoform in humans that is localized to mitochondria. Acanthocytosis, the occurrence of...
Pantothenate kinase-associated neurodegeneration (PKAN) is an early onset and severely disabling neurodegenerative disease for which no therapy is available. PKAN is caused by mutations in PANK2, which encodes for the mitochondrial enzyme pantothenate kinase 2. Its function is to catalyze the first limiting step of Coenzyme A (CoA) biosynthesis. We generated induced pluripotent stem cells from ...
