Development of N2O emission factors derived from nitrification of treated sewage water in rivers
Water Science and Technology, 2023 Because treated sewage water contains nitrogen compounds such as NH4-N and NO2+3-N, nitrous oxide (N2O) which is one of the greenhouse gases is generated by nitrification and denitrification reactions in rivers.

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Pseudomonas knackmussii bioaugmenting nitrification under phenol stress
上海师范大学学报. 自然科学版Most municipal wastewater treatment plants receive and co-treat a portion of industrial wastewater， which often contains some toxic pollutants. These pollutants will seriously inhibit nitrification， making it difficult to meet treatment standards. Taking

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Soil Nitrification Rate Is Affected by Plant Species and Nitrogen Levels
AgricultureThe soil nitrification rate is significantly affected by plant species, and it is also modulated by different nitrogen levels in the soil. There are a wide range of plant species with the capacity to produce biological nitrification inhibitors (hereafter

Effect of Influent COD/N Ratio on Nitrification Rate in a Bench-scale Biological Reactor [PDF]
آب و فاضلاب, 2005 Nitrification, the oxidation of ammonia to nitrate catalyzed by bacteria, is a key part of the global nitrogen cycle. In the first step of nitrification, chemolithoautotrophic ammonia oxidizers transform ammonia to nitrite, which subsequently oxidizes to

Dicyandiamide as nitrification inhibitor of pig slurry ammonium nitrogen in soil
Ciência Rural, 2016 : Inhibition of nitrification of ammoniacal nitrogen pig slurry after its application to the soil can mitigate nitrogen (N) losses by nitrate (NO3 -) denitrification and leaching, with economical and environmental benefits.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
