Quasimolecular structure in elastic O16 + O16 scattering [PDF]

open access: yes, 2006
It is suggested that the experimentally observed intermediate structure in the cross section of elastic O16 + O16 scattering is due to quasibound molecular states of the ion-ion system while the gross structure originates from virtually bound molecular ...

Rovibrational eigenenergy structure of the [H,C,N] molecular system [PDF]

open access: yes, 2011
The vibrational-rotational eigenenergy structure of the [H,N,C] molecular system is one of the key features needed for a quantum mechanical understanding of the HCN reversible arrow HNC model reaction. The rotationless vibrational structure corresponding

Aux/IAA Gene Family in Plants: Molecular Structure, Regulation, and Function

open access: yesInternational Journal of Molecular Sciences, 2018
Auxin plays a crucial role in the diverse cellular and developmental responses of plants across their lifespan. Plants can quickly sense and respond to changes in auxin levels, and these responses involve several major classes of auxin-responsive genes ...

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

Molecular mechanism of influenza A NS1-mediated TRIM25 recognition and inhibition

open access: yesNature Communications, 2018
NS1 of influenza A virus inhibits TRIM25 activity, which is an E3 ligase important for induction of the interferon response. Here, Koliopoulos et al. present structures of TRIM25 and NS1 and show how NS1 binding interferes with substrate recognition of ...

The simple emergence of complex molecular function [PDF]

open access: yesarXiv, 2021
At odds with a traditional view of molecular evolution that seeks a descent-with-modification relationship between functional sequences, new functions can emerge {\it de novo} with relative ease. At early times of molecular evolution, random polymers could have sufficed for the appearance of incipient chemical activity, while the cellular environment ...

First-Principles Based Matrix-Green's Function Approach to Molecular Electronic Devices: General Formalism

open access: yes, 2001
Transport in molecular electronic devices is different from that in semiconductor mesoscopic devices in two important aspects: (1) the effect of the electronic structure and (2) the effect of the interface to the external contact. A rigorous treatment of

Encapsulation kinetics and dynamics of carbon monoxide in clathrate hydrate. [PDF]

open access: yes, 2014
Carbon monoxide clathrate hydrate is a potentially important constituent in the solar system. In contrast to the well-established relation between the size of gaseous molecule and hydrate structure, previous work showed that carbon monoxide molecules ...

Hydrogen-bonded frameworks for molecular structure determination

open access: yesNature Communications, 2019
Single crystal X-ray diffraction is arguably the most definitive method for molecular structure determination, but the inability to grow suitable single crystals can frustrate conventional X-ray diffraction analysis.

Functional variation among LPMOs revealed by the inhibitory effects of cyanide and buffer ions

open access: yesFEBS Letters, EarlyView.
This study addresses the inhibition of lytic polysaccharide monooxygenases (LPMOs) by cyanide and explains how and why the magnitude of observed inhibitory effects depends on the way LPMO reactions are setup and on the type of LPMO. Enzymes known as lytic polysaccharide monooxygenases (LPMOs) are mono‐copper polysaccharide‐degrading peroxygenases that ...
