Isoniazid acetylating phenotype in patients with paracoccidioidomycosis and its relationship with serum sulfadoxin levels, glucose-6-phosphate dehydrogenase and glutathione reductase activities
(1991-12-01)
The authors evaluated the isoniazid acetylating phenotype and measured hematocrit, hemoglobin, glucose-6-phosphate dehydrogenase and glutathione reductase activities plus serum sulfadoxin levels in 39 patients with ...

Application methods of Azospirillum brasilense in first- and second-crop corn
(Univ Federal Campina Grande, 2019-11-01)
This study investigated whether inoculation of Azospirillum brasilense in the seeds or sowing furrow could reduce the need for nitrogen fertilizer application in the corn grown in the first and second crop harvest. The ...
Substrate binding to a nitrite reductase induces a spin transition
(American Chemical Society, 2010-04)
The multiheme enzyme nitrite reductase catalyzes a 6-electron reduction of nitrite to ammonia. The reaction is initiated by substrate binding to the free axial position of the high spin penta-coordinated heme active site. ...

Rapid and slow modulation of nitrate reductase activity in the red macroalga Gracilaria chilensis (Gracilariales, Rhodophyta): influence of different nitrogen sources
(SPRINGER, 2008)
Nitrate is one of the most important stimuli in nitrate reductase (NR) induction, while ammonium is usually an inhibitor. We evaluated the influence of nitrate, ammonium or urea as nitrogen sources on NR activity of the ...
The role of Opaque2 in the control of lysine-degrading activities in developing maize endosperm
(Amer Soc Plant PhysiologistsRockvilleEUA, 1999)
Antiproliferative and quinone reductase-inducing activities of withanolides derivatives
(Elsevier Masson, 2014-05)
Two new and five known withanolides (jaborosalactones 2, 3, 4, 5, and 24) were isolated from the leaves of Jaborosa runcinata Lam. We also obtained some derivatives from jaborosalactone 5, which resulted to be the major ...
Nitric oxide inhibits nitrate reductase activity in wheat leaves
(Elsevier Masson, 2011-02)
Nitrate reductase (NR), a committed enzyme in nitrate assimilation, is involved in the generation of nitric oxide (NO) in plants. In wheat leaf segments exposed to sodium nitroprusside (SNP) or S-nitrosoglutathione (GSNO), ...
