Heterogeneity of the rat NADH-cytochrome-b5-reductase transcripts resulting from multiple alternative first exons

Autor: Axel Kahn, Alena Leroux, Jean Claude Kaplan, Luisa Mota Vieira

Publikováno v: European Journal of Biochemistry. 220:729-737

In order to understand the mechanisms responsible for the generation of different isoforms (membrane-bound and soluble) of NADH-cytochrome b5 reductase, and the different clinical forms of recessive congenital methemoglobinemia due to the deficiency

Prenatal diagnosis of recessive congenital methaemoglobinaemia type II: novel mutation in the NADH-cytochrome b5 reductase gene leading to stop codon read-through

Autor: Alena Leroux, France Leturcq, Nathalie Deburgrave, Marie-France Szajnert

Publikováno v: European journal of haematology. 74(5)

A case of type II recessive congenital methaemoglobinaemia (RCM) observed in a Lebanese subject with a novel mutation in NADH-cytochrome b5 reductase gene is described. A homozygous mutation CAC to AA identified at Thr 295 with an out-of-frame 1-bp d

Prenatal diagnosis of congenital enzymopenic methaemoglobinaemia with mental retardation due to generalized cytochrome b5 reductase deficiency: First report of two cases

Autor: J. C. Kaplan, Claudine Junien, André Boué, Joëlle Boué, D. Lostanlen, H. Nicolas, Alena Leroux, A. Reghis

Publikováno v: Prenatal Diagnosis. 1:17-24

Prenatal diagnosis of congential enzymopenic methaemoglobinaemia (CEM) with mental retardation was performed in two fetuses at risk for generalized NADH-cytochrome b5 reductase deficiency. In the first case the enzyme activity of cultured amniotic ce

Regulation of protein synthesis by phosphorylation of eukaryotic initiation factor 2 alpha in intact reticulocytes and reticulocyte lysates

Autor: Irving M. London, Alena Leroux

Publikováno v: Proceedings of the National Academy of Sciences. 79:2147-2151

Studies in intact rabbit reticulocytes and reticulocyte lysates provide further evidence of a functional role for the phosphorylation of eukaryotic initiation factor 2 alpha (eIF-2 alpha) in the regulation of initiation of protein synthesis in eukary

Publikováno v: Acta Haematologica. 56:174-182

Three brothers with congenital recessive methaemoglobinaemia without mental retardation were found to be homozygous for NADH diaphorase deficiency. Twelve family members were heterozygous. One of the

Site-specific phosphorylation of the α subunit of eukaryotic initiation factor eIF-2 by the heme-regulated and double-stranded RNA-activated eIF-2α kinases from rabbit reticulocyte lysates

Autor: Irving M. London, Alena Leroux, Vivian Ernst, Daniel H. Levin

Publikováno v: Proceedings of the National Academy of Sciences. 77:1286-1290

The site specificity of phosphorylation of the α subunit of eukaryotic initiation factor 2 (eIF-2α) by the heme-regulated and double-stranded RNA-activated eIF-2α kinases were compared by phosphopeptide mapping. eIF-2α was maximally phosphorylate

Soluble NADH-cytochrome b5 reductase from rabbit liver cytosol: partial purification and characterization

Autor: Jean-Claude Kaplan, Alena Leroux, D. Lostanlen, A. Vieire De Barros

Publikováno v: Biochimica et biophysica acta. 526(1)

A soluble form of NADH-cytochrome b5 reductase (NADH: ferricytochrome b5 oxidoreductase, EC 1.6.2.2) was found in the cytosolic fraction of rabbit liver. The partially purified enzyme was strictly specific for NADH. It catalyzed the reduction of seve

Autor: Jean-Claude Kaplan, Lech Torlinski, Alena Leroux

Publikováno v: Biochimica et biophysica acta. 481(1)

In congenital methemoglobinemia associated with mental retardation a generalized deficiency of NADH-cytochrome beta 5 reductase (NADH : ferricytochrome beta 5 oxidoreductase, EC 1.6.2.2) has been found in soluble extracts of red blood cells, as well
