Translophagy—A potential link between autophagy impairment and translational errors
FEBS Letters, EarlyView.Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Mycena luxaustralis , a new bioluminescent species in section Sacchariferae from southern Chile
Plant and Fungal SystematicsBioluminescent fungi emit light through chemical luminescence of fungal tissues. More than 100 species of bioluminescent fungi have been described in five distinct groups of Agaricales : Omphalotus , Armillaria , the Lucentipes lineage within ...

A NEW SPECIES OF EUDAMUS [PDF]
The Canadian Entomologist, 1892 Eudamus coyate: Expands 2⅛i inches. Primaries dark glossy brown, several shades darker than Eudam. bathyllus; fringes of same colour as the wings. The apices of the wings run more to a point than in other species of the genus. There are no markings on the primaries, although there are some very faint indications of markings, which are not brought out ...

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.

A NEW SPECIES OF NEONYMPHA [PDF]
The Canadian Entomologist, 1889 Neonympha Mitchellii n. sp.Male.—Upper surface grayish wood-brown, rather dark, without spots or marks, except that the spots on the underside of the hind wings and the dark lines bordering the terminal dark yellow line on the same wings show through a little. Fringes concolorus, in certain lights a little smoky tinged.

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 ...

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 ...

A NEW SPECIES OF ASTEROSCOPUS [PDF]
The Canadian Entomologist, 1899 Lederer characterizes Asteroscopus essentially as follows: Narrow-winged owlets, resembling Bombycids in the shaggy, loose vestiture. Palpi short, not exceeding the front, drooping. Tongue short and weak. Eyes naked, with bristly lashes. Antennæ comparatively long, with a tuft of hair at the base; in the male with short pectinations to the tip; in the ...
