Modification of ground state chemical reactivity via light-matter coherence in infrared cavities [PDF]

open access: yes, 2023
Reaction-rate modifications for chemical processes have been reported due to strong coupling between reactant molecular vibrations and the cavity vacuum, however, no accepted mechanisms explain these observations.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Conceptual DFT as a chemoinformatics tool for the study of the Taltobulin anticancer peptide

open access: yesBMC Research Notes, 2019
Objective A well-behaved model chemistry previously validated for the study of the chemical reactivity of peptides was considered for the calculation of the molecular properties and structure of the Taltobulin anticancer peptide.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS 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 ...

Phenomenological chemical reactivity theory for mobile electrons

open access: yes, 2010
We present herein a model to deal with the chemical reactivity, selectivity and site activation concepts of p electron systems derived by merging the classical Coulson–Longuet-Higgins response function theory based on the Hu¨ckel molecular orbital ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Chemical graphs enumeration and chemical reactivity: thermodynamic and kinetic considerations

open access: yes, 1988
Recent interplay between the enumeration of chemical graphs and the theory of chemical reactivity based on stationary points of the potential energy hypersurface is surveyed.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...
