New and Improved Diagnostics for Detection of Drug-Resistant Pulmonary Tuberculosis. [PDF]

, 2011
PURPOSE OF REVIEW: Tuberculosis (TB) remains a global emergency and continues to kill 1.7 million people globally each year. Drug-resistant TB is now well established throughout the world and most TB patients are not being screened for drug resistance ...

Drought-induced effects on nitrate reductase activity and mRNA and on the coordination of nitrogen and carbon metabolism in maize leaves

Plant Physiology, 1998
Maize (Zea mays L.) plants were grown to the nine-leaf stage. Despite a saturating N supply, the youngest mature leaves (seventh position on the stem) contained little NO3- reserve.

Denitrification, activity of bacterial flocs, and growth of a filamentous bacterium in relation with the bulking of activated sludge [PDF]

, 1978
Activated sludge with poor settling characteristics is caught under the term "bulking" sludge. Various types of bulking activated sludge can be distinguished.1) Sludge containing an abundance of filamentous microorganisms.2) Sludge, characterized by ...

Modeling the effect of copper availability on bacterial denitrification [PDF]

, 2013
When denitrifying bacteria such as Paracoccus denitrificans respire anaerobically they convert nitrate to dinitrogen gas via a pathway which includes the potent greenhouse gas, nitrous oxide (NO). The copper-dependent enzyme Nitrous Oxide reductase (Nos)

Post-translational regulation of nitrate reductase: mechanism, physiological relevance and environmental triggers.

Journal of Experimental Botany, 2001
Assimilatory nitrate reductase (NR) of higher plants is a most interesting enzyme, both from its central function in plant primary metabolism and from the complex regulation of its expression and control of catalytic activity and degradation.

Photo‐controlled Release of Urea Enables the Detection of Urea‐Urease Intermediates by cryo‐FTIR

Angewandte Chemie International Edition, Accepted Article.
Caged compounds are a valuable tool to photocontrol the release of enzymatic substrates in a reaction. For example, caged urea molecules were proposed to control urea delivery to urease reactions and aid the determination of the catalytic mechanism of this enzyme.

Seasonal variation in the nitrogen metabolism of young Scots pine.

Silva Fennica, 1988
Seasonal changed in total nitrogen, protein, amino acid, ammonia, nitrate and nitrite concentrations, and nitrate reductase and γ-glutamyltransferase activities in the needles, buds and shoots of young Scots pine ( L.) were studied.
