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

FEBS 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 ...

Culm age mediates trait coordination and responses of rhizome roots to soil moisture status and nitrogen addition in Moso bamboo (

Advances in Bamboo Science
Root economic strategies are well characterized across species, but their variation across developmental stages within species remains poorly understood, especially in clonal plants with connected ramets of different ages.

RNA‐related functions of BRCA2 in transcription, replication, and genome stability

FEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Interspecific coordination and intraspecific plasticity of fine root traits in North American temperate tree species

Frontiers in Plant Science, 2013
Fine roots play an important role in nutrient and water absorption and hence overall tree performance. However, current understanding of the ecological role of belowground traits lags considerably behind those of aboveground traits.

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Lag Length Selection for Unit Root Tests in the Presence of Nonstationary Volatility [PDF]

A number of recently published papers have focused on the problem of testing for a unit root in the case where the driving shocks may be unconditionally heteroskedastic.

Responses of belowground fine root biomass and morphology in Robinia pseudoacacia L. plantations to aboveground environmental factors

Global Ecology and Conservation
The adaptation of fine roots to a variety of environmental conditions is crucial for promoting the growth and long-term survival of forest trees. To achieve sustainable forest ecology management requires a comprehensive understanding of the intricate ...

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

FEBS 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.

Fine root morphological characteristics and biomass distribution characteristics of different artificial forests in coastal salt land and their influencing factors

Frontiers in Plant Science
To elucidate the ecological adaptations of fine root morphological traits and biomass in tree species with different life forms to coastal saline soil, five species (Robinia pseudoacacia(RP), Sapium sebiferum(SA), Salix matsudana(SM), Quercus virginiana ...
