Structural and biochemical analysis of a B12 superbinder

FEBS 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.

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

FEBS 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 ...

Insufficiency of Thyroid Hormone in Frog Metamorphosis and the Role of Glucocorticoids

Frontiers in Endocrinology, 2019
Thyroid hormone (TH) is the most important hormone in frog metamorphosis, a developmental process which will not occur in the absence of TH but can be induced precociously by exogenous TH.

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 ...

Hologenomic rewiring facilitates dietary adaptation to chitin-rich marine resources in the crab-eating frog

Frontiers in Zoology
Background Secondary adaptation of amphibians to marine environments is exceptionally rare. The crab-eating frog, Fejervarya cancrivora, is the only known amphibian capable of completing its life cycle in intertidal zones, where it faces dual challenges:

Plant phenological functional types shape soil nematode abundance and function by regulating aboveground biomass and soil dissolved organic carbon in tropical Xishuangbanna

Geoderma
Plant-soil interactions in terrestrial ecosystems profoundly shape the structure and function of belowground communities. Soil nematodes play a vital role in facilitating key belowground ecological processes, however, it remains poorly understood how ...

Prospecting the protein design landscape

FEBS 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.
