Interplay between Beryllium Bonds and Anion-π Interactions in BeR2:C6X6:Y− Complexes (R = H, F and Cl, X = H and F, and Y = Cl and Br)

Molecules, 2015
A theoretical study of the beryllium bonds in BeR2:C6X6 (R = H, F, Cl and X = H and F) has been carried out by means of MP2/aug′-cc-pVDZ computational methods. In addition, the ternary complexes BeR2:C6X6:Y− (Y = Cl and Br) have been analyzed. Geometric,

Noncovalent Bonds through Sigma and Pi-Hole Located on the Same Molecule. Guiding Principles and Comparisons

Molecules, 2021
Over the last years, scientific interest in noncovalent interactions based on the presence of electron-depleted regions called σ-holes or π-holes has markedly accelerated.

Functional (un)cooperativity in elevator transport proteins.

, 2020
The activity of enzymes is subject to regulation at multiple levels. Cooperativity, the interconnected behavior of active sites within a protein complex, directly affects protein activity.

A high-cooperativity confocal cavity QED microscope

, 2022
Cavity QED with cooperativity far greater than unity enables high-fidelity quantum sensing and information processing. The high-cooperativity regime is often reached through the use of short, single-mode resonators. More complicated multimode resonators,

Sequencing and Cooperation [PDF]

Operations Research, 1994
In machine scheduling the first problem is to find a timetable that is optimal with respect to some efficiency criterion. If the jobs come from different clients the solution of the optimization problem is not the end of the story. In addition, we have to decide how the minimal total cost must be distributed among the parties involved.

Allosteric binding cooperativity in a kinetic context [PDF]

, 2023
Allosteric modulators are of prime interest in drug discovery. These drugs regulate the binding and function of endogenous ligands, with some advantages over orthosteric ligands.

Origin of cooperativity in hydrogen bonding

, 2017
Hydrogen bond cooperativity results from interactions between effective point dipoles which account for many-body contributions to cooperativity.

Cooperative or Uncooperative Cooperatives? Digging into the Process of Cooperation in Food and Agriculture Cooperatives [PDF]

Journal of Agriculture, Food Systems, and Community Development, 2018
Cooperative organizing around food and agricul­ture is nothing new (Knupfer, 2013). However, there has been a recent resurgence of interest in the cooperative legal form. This research has followed this rebirth in a region in the western United States where rural producers and urban consumers, gentrifying communities of color, and environ­mentally ...

Role of Fluctuations in Ligand Binding Cooperativity of Membrane Receptors [PDF]

, 2011
Signal transduction upon binding of a ligand to a membrane protein can occur not only via allosteric conformational changes but also through fluctuations. We report a numerical study on the influence of conformational fluctuations on the cooperativity of

Single-molecule methods for characterizing receptor dimers reveal metastable opioid receptor homodimers that induce functional modulation

Nature Communications
Opioid receptors (ORs) are critical for endogenous and synthetic analgesics. OR homodimerization is considered important for their pharmacological diversity, but whether they form homodimers remains controversial.
