A carbon-nitrogen negative feedback loop underlies the repeated evolution of cnidarian–Symbiodiniaceae symbioses

open access: yesNature Communications, 2023
Symbiotic associations with Symbiodiniaceae have evolved independently across a diverse range of cnidarian taxa including reef-building corals, sea anemones, and jellyfish, yet the molecular mechanisms underlying their regulation and repeated evolution ...

Cycles of carbon, nitrogen and phosphorus in poultry manure management technologies – environmental aspects

open access: yesCritical reviews in environmental science and technology, 2022
Poultry manure (PM) has become a serious environmental problem due to large scale of industrial production and unsustainable management, causing emissions of greenhouse gases (GHGs), odors, leakage of nutrients as well as inorganic, organic and ...

Anoxia decreases the magnitude of the carbon, nitrogen, and phosphorus sink in freshwaters

open access: yesGlobal Change Biology, 2021
Oxygen availability is decreasing in many lakes and reservoirs worldwide, raising the urgency for understanding how anoxia (low oxygen) affects coupled biogeochemical cycling, which has major implications for water quality, food webs, and ecosystem ...

Carbon-Nitrogen bond formation on Cu electrodes during CO2 reduction in NO3- solution

open access: yesSocial Science Research Network, 2021
In performing electrochemical reduction of CO2 over Cu electrodes, the anions present in solution typically do not participate in the formation of reaction products.

Characterisation of the Cullin-3 mutation that causes a severe form of familial hypertension and hyperkalaemia [PDF]

open access: yes, 2015
Deletion of exon 9 from Cullin‐3 (CUL3, residues 403–459: CUL3Δ403–459) causes pseudohypoaldosteronism type IIE (PHA2E), a severe form of familial hyperkalaemia and hypertension (FHHt).

Molecular characterization and analysis of the acrB gene of Aspergillus nidulans: A gene identified by genetic interaction as a component of the regulatory network that includes the CreB deubiquitination enzyme [PDF]

open access: yes, 2003
Copyright © 2003 by the Genetics Society of AmericaMutations in the acrB gene, which were originally selected through their resistance to acriflavine, also result in reduced growth on a range of sole carbon sources, including fructose, cellobiose ...

Discovery of Amide (Peptide) Bond Synthetic Activity in Acyl-CoA Synthetase*

open access: yesJournal of Biological Chemistry, 2008
Acyl-CoA synthetase, which is one of the acid-thiol ligases (EC 6.2.1), plays key roles in metabolic and regulatory processes. This enzyme forms a carbon-sulfur bond in the presence of ATP and Mg2+, yielding acyl-CoA thioesters from the corresponding ...

Improved catalytic activity of ruthenium–arene complexes in the reduction of NAD+ [PDF]

open access: yes, 2012
A series of neutral Ru-II half-sandwich complexes of the type [(eta(6)-arene)Ru(N,N')Cl] where the arene is para-cymene (p-cym), hexamethylbenzene (hmb), biphenyl (bip), or benzene (bn) and N,N' is N-(2-aminoethyl) -4-(trifluoromethyl)benzenesulfonamide (

Regulation of senescence under elevated atmospheric CO2 via ubiquitin modification

open access: yesPlant Signalling & Behavior, 2014
Elevated atmospheric CO2 concentration is a serious global environmental problem. Elevated CO2 affects plant growth by changing primary metabolism, closely related to carbon (C) and nitrogen (N) availability.
