Electron Affinities of the Early Lanthanide Monoxide Molecules

open access: yes, 2011
Electron Affinities of the Early Lanthanide Monoxide MoleculesThe photoelectron imagings of LaO(-), CeO(-), PrO(-), and NdO(-) at 1064 nm are reported. The well resolved photoelectron spectra allow the electron affinities to be determined as 0.99(1) eV ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Elevational patterns of the percentages of plant genera with tropical and temperate affinities in Nepal [PDF]

open access: yesPeerJ, 2019
Background Geographical patterns of species diversity are one of the key topics in biogeography and ecology. The effects of biogeographical affinities on the elevational patterns of species diversity have attracted much attention recently, but the ...

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Affinities among living dormouse genera

open access: yesHystrix, the Italian Journal of Mammalogy, 1995
<strong>Abstract</strong> This paper focuses on relationships among the living Palaearctic myoxid genera, excluding the African hystricomorphous graphiurines. Features of the dental occlusal pattern, skull, enamel ultrastructure of the lower

The complete chloroplast genome of Verbascum thapsus L. (Scrophulariaceae) and its phylogenetic affinities

open access: yesMitochondrial DNA. Part B. Resources, 2022
Verbascum thapsus L. has extensive pharmacological effects, including antioxidative and antineoplastic action, memory improvement and neuroprotection. However, its phylogenetic position is not established in Scrophulariaceae.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
