Regulación simbiótica de la expresión del sistema hidrogenasa por NifA en R. leguminosarum bv. viciae
… de RpoN, de IHF y del activador transcripcional NifA. La activación dependiente de NifA de P1, fue corroborada en el fondo genético de K.pneumoniae mediante experimentos de inhibición de la nitrogenasa por múltiples copias de P1, y en el fondo de R.etli utilizando mutantes nifA en simbiosis con …

Genetic analysis of nifF and nifA and site-directed mutagenesis of nifE in Azotobacter vinelandii
… gene products. The nifF (electron transport), nifA (nif gene regulation) and nifE (FeMo-cofactor biosynthesis) genes from <i>Azotobacter vinelandii</i> were genetically analyzed. The nucleotide sequence of the nifF gene, which encodes a flavodoxin, was determined. Specific mutation strains …

Molekularbiologische und genetische Untersuchungen zur Regulation des zentralen Regulators der Stickstofffixierung NifA in Rhizobium leguminosarum bv. viciae VF39
… the regulation of nif and fix gene expression is NifA. This work presents, that two promotors are involved in nifA gene expression in Rhizobium leguminosarum bv. viciae VF39, namely P1, located at the downstream end of fixX and PfixA, the promotor of the fixA gene, located 3600bp upstream of P1. …

Regulation of nitrogen fixation in <i>Klebsiella pneumoniae</i>: Nitrogen and oxygen signal perception by the negative regulator NifL
… der nif - spezifische Transkriptionsaktivator NifA als Reaktion auf molekularen Sauerstoff und Ammonium durch NifL gehemmt. Die Komplexbildung zwischen NifL und NifA (etwa 1:1-Verhältnis) erfolgt, wenn die Synthese der beiden Proteine in Gegenwart von Sauerstoff und / oder Ammonium stattfindet. …

Regulation of nitrogen fixation in Klebsiella pneumoniae: NifL, one protein transducing two environmental signals to the nif-transcriptional activator NifA
… NifL die Aktivität des Transkriptionsaktivators NifA in Abhängigkeit der Umweltsignale Stickstoff und Sauerstoff. NifL ist ein Flavoprotein, welches das Sauerstoffsignal wahrscheinlich durch einen redoxsensitiven Konformationswechsel transduziert. Wir haben die Redoxeigenschaften von NifL, …

Regulation of nitrogen fixation in <i>Klebsiella pneumoniae</i>: The role of Fnr in oxygen signal-transduction
… wird die Aktivität des Transkriptionsaktivators NifA durch NifL in Abhängigkeit von gebundenem Stickstoff und molekularem Sauerstoff geregelt. NifL, ein Flavoprotein, das redox-sensitiv ist, scheint, das Sauerstoffsignal über eine Konformationsänderung auf NifA zu übertragen. Kürzlich konnten wir …

Mutagenesis of nifE and nifN from Azotobacter vinelandii
… mutant strains which carry lesions in nifH or nifA in addition to the nifN

Coordination of Carbon Dioxide and Nitrogen Metabolism in Rhodobacter sphaeroides
… of the transcriptional regulator of nitrogenase, NifA, contributed to its post-translational response to cellular nitrogen status. Finally, the reciprocal response of the CBB cycle to nitrogenase activity was investigated determining that the expression of the genes of the CBB cycle was repressed …

Análise filogenética do gênero Formicivora Swainson, 1825 (Aves: Passeriformes: Thamnophilidae) baseada em caracteres morfológicos e vocais
… of the genus. Stymphalonlis acutirostris, F. nifa and F. grisea fonn a clade that is the sister group to a clade fonned by F. melanogaster, F. serrana and F. littoralis. The sister group to Fomricivora could not be unambiguously hypothesized. While the phylogenetic relationships of F. iheringi …

A Dynamic Decision Support System for Drought Resiliency and Climate Change
… project titled Water for the Seasons (USDA/NIFA Grant No. 1360505/1360506). Both scenarios are based on the same concatenation of two historic droughts, creating a 13-year dry period. One has been calibrated to current temperature profiles, and the other to projected temperatures for the …
