SecA mediates cotranslational targeting and translocation of an inner membrane protein

Journal of Cell Biology, 2017
Protein targeting to the bacterial plasma membrane was generally thought to occur via two major pathways: cotranslational targeting by signal recognition particle (SRP) and posttranslational targeting by SecA and SecB.

Temporal dynamics in functional fruit traits of native and invasive fleshy fruited plants in subtropical Andean forests

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruits encompass the energetic and material flow between both interacting parties in frugivore‐mediated seed dispersal. Since fruit traits matter in frugivores' foraging decisions, the temporal dynamics of fruit traits might influence interaction outcomes.

Reduced-Order Model for Catalytic Cracking of Bio-Oil

Fluids
This work presents a one-dimensional (1D) model for simulating the behavior of an FCC riser reactor processing bio-oil. The FCC riser is modeled as a plug-flow reactor, where the bio-oil feed undergoes vaporization followed by catalytic cracking ...

Single-molecule observation of nucleotide induced conformational changes in basal SecA-ATP hydrolysis

Science Advances, 2018
We visualize ATP-driven domain dynamics of individual SecA molecules in a near-native setting using atomic force microscopy. SecA is the critical adenosine triphosphatase that drives preprotein transport through the translocon, SecYEG, in Escherichia ...

Functional traits predict changes in floral phenology under climate change in a highly diverse Mediterranean community

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants are shifting their flowering phenology in response to climate change, but trends differ between species and communities. Functional traits can largely explain how different species respond to climate change by shifting their phenology, and can therefore help ...

Yet another job for the bacterial ribosome

Microbial Cell, 2019
The ribosome is a sophisticated cellular machine, composed of RNA and protein, which translates the mRNA-encoded genetic information into protein and thus acts at the center of gene expression. Still, the ribosome not only decodes the genetic information,

Novel Sequence Feature of SecA Translocase Protein Unique to the Thermophilic Bacteria: Bioinformatics Analyses to Investigate Their Potential Roles

Microorganisms, 2019
SecA is an evolutionarily conserved protein that plays an indispensable role in the secretion of proteins across the bacterial cell membrane. Comparative analyses of SecA homologs have identified two large conserved signature inserts (CSIs) that are ...

Sitting Less, Moving More: A Compositional Data Analysis of Movement Behaviours and Adolescent Health‐Related Quality of Life

Acta Paediatrica, EarlyView.
ABSTRACT Aim To predict changes in health‐related quality of life (HRQoL) when sedentary behaviour was hypothetically replaced with other movement behaviours (sleep, standing, light physical activity and moderate‐to‐vigorous physical activity) in adolescents.
