Both Inter- and Intramolecular Coupling of O-H Groups Determine the Vibrational Response of the Water/Air Interface [PDF]
, 2016 Vibrational coupling is relevant not only for dissipation of excess energy after chemical reactions but also for elucidating molecular structure and dynamics. It is particularly important for OH stretch vibrational spectra of water, for which it is known that in bulk both intra- and intermolecular coupling alter the intensity and line shape of the ...

Analyzing intramolecular dynamics by Fast Lyapunov Indicators [PDF]
The Journal of Chemical Physics 121, 8 (2004) 3471, 2009 We report an analysis of intramolecular dynamics of the highly excited planar carbonyl sulfide (OCS) below and at the dissociation threshold by the Fast Lyapunov Indicator (FLI) method. By mapping out the variety of dynamical regimes in the phase space of this molecule, we obtain the degree of regularity of the system versus its energy. We combine this

Molecular Microbiology, EarlyView.Iron is essential for life, yet excessive levels can quickly lead to cellular damage via oxidative stress, underscoring the need for global regulators of iron and heme homeostasis. In this study, we present a genome‐wide analysis of the binding patterns of DtxR and HrrA in Corynebacterium glutamicum.

Periplasmic protein thiol:disulfide oxidoreductases of Escherichia coli [PDF]
, 2017 Disulfide bond formation is part of the folding pathway for many periplasmic and outer membrane proteins that contain structural disulfide bonds. In Escherichia coli, a broad variety of periplasmic protein thiol:disulfide oxidoreductases have been ...

Stellar metallicity is a key parameter for the search of Life in the Universe [PDF]
arXiv, 2022 The search for Life in the Universe generally assumes three basic life's needs: I) building block elements (i.e., CHNOPS), II) a solvent to life's reactions (generally, liquid water) and III) a thermodynamic disequilibrium. It is assumed that similar requirements might be universal in the Cosmos.

Crop Science, Volume 65, Issue 3, May/June 2025.Abstract Sorghum is the third most important food crop, grown on nearly 40 million ha globally, and is known for its resilience under unfavorable conditions. Sorghum is reported to have a strong biological nitrification inhibition (BNI) capacity in root systems, a plant function that suppresses soil nitrifier activity, which in turn prevents the ...

Quantum coherent contributions in biological electron transfer [PDF]
arXiv, 2011 Many biological electron transfer (ET) reactions are mediated by metal centres in proteins. NADH:ubiquinone oxidoreductase (complex I) contains an intramolecular chain of seven iron-sulphur (FeS) clusters, one of the longest chains of metal centres in biology and a test case for physical models of intramolecular ET.

ChemistrySelect, Volume 10, Issue 17, May 5, 2025.A new set of spirooxindole‐ and spiroindenoquinoxaline‐derived pyrrolo[3,4‐c] pyrroles has been synthesized through atom‐economic one‐pot multicomponent reactions. Based on the results, compounds 4b and 5a demonstrated promising Glide scores and exhibited strong binding affinity with decaprenylphosphoryl‐β‐D‐ribofuranose oxidoreductase.
