Structural and mechanistic basis for the regulation of the chloroplast signal recognition particle by (p)ppGpp

FEBS Letters, EarlyView.
LHCPs are transported to the thylakoid membrane via the (cp)SRP pathway. This process involves a transit complex of (cp)SRP43, (cp)SRP54 and LHCP, which interacts with (cp)FtsY and Alb3 at the membrane. GTP hydrolysis by (cp)SRP54 and (cp)FtsY triggers complex dissociation.

Seasonal variability of Crvena river water mineralization [PDF]

Glasnik Srpskog Geografskog Društva, 2010
The mineralization of water and its content in Crvena River so far have not been studied. Water sampling was conducted from April 2008 - May 2009. Total mineralization is relatively low, which is consistent with the dominant lithological structure ...

Integer quantum Hall conductivity and longitudinal conductivity in silicene under the electric field and magnetic field [PDF]

, 2018
We investigate the integer Hall conductivity and longitudinal conductivity of silicene under the magnetic field, electric field, and exchange field in this letter. We focus not only on the low-temperature and $\delta$-function impurities (i.e., independent of the scattering momentum) case, which only exist the intra-Landau level transition, but also on

Heat conduction in deformable Frenkel-Kontorova lattices: thermal conductivity and negative differential thermal resistance [PDF]

Phys. Rev. E 83 (2011)011131, 2011
Heat conduction through the Frenkel-Kontorova (FK) lattices is numerically investigated in the presence of a deformable substrate potential. It is found that the deformation of the substrate potential has a strong influence on heat conduction. The thermal conductivity as a function of the shape parameter is nonmonotonic.

Taurine promotes glucagon‐like peptide‐1 secretion in enteroendocrine L cells

FEBS Letters, EarlyView.
Taurine, a sulfur‐containing amino acid, is likely taken up by enteroendocrine L cells via the taurine transporter. This process increases the levels of cytosolic ATP. The increase in intracellular Ca2+ concentrations and glucagon‐like peptide‐1 secretion through membrane depolarization is caused by the closure of ATP‐sensitive potassium channels ...

Ionic conductivity and dielectric studies of LiClO4 doped poly(vinylalcohol)(PVA)/chitosan(CS) composites [PDF]

Journal of Advanced Dielectrics, 2014
This paper focuses on the dielectric constant (ε′), dielectric loss factor (ε″) and frequency dependent conductivity (σac) properties of newly prepared poly(vinylalcohol) (PVA) chitosan (CS) composite films incorporated with different concentrations of ...

The multiple roles of the NlpC_P60 peptidase family in mycobacteria – an underexplored target for antimicrobial drug discovery

FEBS Letters, EarlyView.
The NlpC_P60 superfamily of peptidases is recognised by its key role in bacterial cell wall homeostasis. Recently, studies have also described the involvement of NlpC_P60‐like enzymes in bacterial competitive mechanisms and pathogenesis across several lineages.

Unraveling Mycobacterium tuberculosis acid resistance and pH homeostasis mechanisms

FEBS Letters, EarlyView.
Mycobacterium tuberculosis exhibits a remarkable resilience to acid stress. In this Review, we discuss some of the molecular mechanisms and metabolic pathways used by the tubercle bacilli to adapt and resist host‐mediated acid stress. Mycobacterium tuberculosis (Mtb) is a successful pathogen that has developed a variety of strategies to survive and ...

Properties of regenerated cellulose films with silver nanoparticles and plasticizers [PDF]

Polímeros
Nanocomposite films from cellulose jute fibers can be promising for application in electronic devices, mainly when silver nanoparticles (AgNPs) are added, which increases their conductivity.

Investigation on electrical conductivity and dielectric property of La0.8Pb0.2(Fe,Ti)0.5O3 ceramic nanoparticles [PDF]

Journal of Advanced Dielectrics, 2019
The modification of the structure lanthanum orthoferrites (LaFeO3) to obtain ceramic materials with enhanced structural, optical, and electrical properties constitutes an active area of research. The preparation of La0.8Pb0.2(Fe, Ti)0.5O3 (LPFTO) ceramic
