Pantothenate studies, II. Evidence from Mutants for interference by salicylate with pantoate synthesis.
Although several workers have observed that the bacteriostatic effect of salicylate can be reversed by pantothenate, there is disagreement about the reaction step affected. Salicylate has been considered to inhibit synthesis of pantoate (Ivanovics, 1942), the conversion of pantoate to pantothenate (Roblin, 1949), and the utilization of pantothenate (Mcllwain, 1943; Work and Work, 1948); Ackeima...
متن کاملStudies on the nutritional requirements of the fusobacteria. II. Requirements for pantothenate and purines.
In a previous study on the nutritional requirements of Fusobacterium nucleatum it was reported that growth factors were present in yeast extract for these microorganisms (Omata, 1953). Further studies were made to elucidate the nature of these growth factors in a simplified medium under different environmental conditions. In this present study it has been found that pantothenic acid, tryptophan...

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.
