Characterization of an NADH oxidase of the flavin-dependent disulfide reductase family from Methanocaldococcus jannaschii.
Methanocaldococcus jannaschii, a deeply rooted hyperthermophilic anaerobic methanarchaeon from a deep-sea hydrothermal vent, carries an NADH oxidase (Nox) homologue (MJ0649). According to the characteristics described here, MJ0649 represents an unusual member within group 3 of the flavin-dependent disulfide reductase (FDR) family. This FDR group comprises Nox, NADH peroxidases (Npx) and coenzym...
متن کاملRibose-5-phosphate biosynthesis in Methanocaldococcus jannaschii occurs in the absence of a pentose-phosphate pathway.
Recent work has raised a question as to the involvement of erythrose-4-phosphate, a product of the pentose phosphate pathway, in the metabolism of the methanogenic archaea (R. H. White, Biochemistry 43:7618-7627, 2004). To address the possible absence of erythrose-4-phosphate in Methanocaldococcus jannaschii, we have assayed cell extracts of this methanogen for the presence of this and other in...
متن کاملAnalysis of nitrate reductase mRNA expression and nitrate reductase activity in response to nitrogen supply
Nitrate is one of the major sources of nitrogen for the growth of plants. It is taken up by plant roots and transported to the leaves where it is reduced to nitrite in the. The main objective of this research was to investigate stimulatory effects of sodium nitrate, potassium nitrate, ammonia and urea on the production/generation of the nitrate reductase mRNA in Triticum aestivum plants. The pl...
متن کاملProtein-coding gene promoters in Methanocaldococcus (Methanococcus) jannaschii
Although Methanocaldococcus (Methanococcus) jannaschii was the first archaeon to have its genome sequenced, little is known about the promoters of its protein-coding genes. To expand our knowledge, we have experimentally identified 131 promoters for 107 protein-coding genes in this genome by mapping their transcription start sites. Compared to previously identified promoters, more than half of ...
متن کاملMethemoglobin Reductase ( Cytochrome b 5 Reductase ) Deficiency in Congenital
Two NADH diaphorases, diaphorase I and II, were isolated from normal red cells and congenital methemoglobinemic red cells by CM-cellulose and DE 32 column chromatography. For methemoglobinemic sample, activities of diaphorase I and diaphorase II were 80% and less than 5% of those for the normal red cells, respectively. Only diaphorase II showed cytochrome b5 reductase activity. The cytochrome b...
