Structural and biochemical analysis of a B12 superbinder

open access: yesFEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Indigenous women's preference for climate change adaptation and aquaculture development to build capacity in the Northern Territory [PDF]

open access: yes, 2013
Research was carried out on South Goulburn Island, Northern Territory, to improve understandings of local, Indigenous people’s dependency on marine resources, and of their perspectives on climate change, and aquaculture as a means towards adapting to ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

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 ...

Opportunity windows accelerate action and expand options for climate adaptation in Europe

open access: yesCommunications Earth & Environment
Climate adaptation must be intensified globally to keep up with increasing climate change impacts. To date, adaptation is mostly driven by climate risks that need to be reduced and little by opportunities. We identify opportunity windows -i.e. favourable

Adaptation and Development: Whose Goals and Priorities Count?

open access: yes, 2010
It has been argued that adaptation to climate change should be integrated with development activities, and that it is time to pursue its 'mainstreaming' within such programmes (Burton 2009).

Prospecting the protein design landscape

open access: yesFEBS Letters, EarlyView.
This review outlines the current state of various protein design approaches. We discuss the current possibilities enabled by recently released tools, highlight future avenues to pursue in protein design, and underscore the crucial role of key databases and resources for successful protein design workflows.

Cloud-powered drought mapping: using satellite-derived indices to track agro-meteorological extremes in Prince Edward Island

open access: yesEgyptian Journal of Remote Sensing and Space Sciences
Climate change and rainfall variability have increased the frequency and intensity of droughts worldwide. It is therefore important to identify when and where droughts are likely to occur to implement effective drought management strategies.

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

open access: yesFEBS 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 ...

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.
