GCN2 in proteostasis: structural logic, signalling networks and disease

open access: yesThe FEBS Journal, EarlyView.
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.

A distinct gene expression mechanism for d‐amino acid utilization in hyperthermophilic archaeon Pyrococcus horikoshii

open access: yesThe FEBS Journal, EarlyView.
The genes PH0137, PH0138, and PH0140 form a cluster in the genome of Pyrococcus horikoshii. The PH0140 gene encodes a transcription factor identified as a d‐amino acid‐responsive regulatory protein (DARP). In feast mode, l‐Ile‐bound DARP binds to the promoter and represses transcription of PH0137 and PH0138. In famine mode, DARP binds to d‐allo‐Ile and

The tryptophan prenyltransferase ComQ from Bacillus subtilis 168 can prenylate daptomycin at Trp1

open access: yesThe FEBS Journal, EarlyView.
ComQ168 from Bacillus subtilis 168 catalyzes C‐terminal tryptophan farnesylation of ComX to generate a competence‐inducing pheromone. Recombinant ComQ168 also modifies cyclic peptides, including Daptomycin, likely at the N‐terminal tryptophan. Structural modeling highlights a C‐terminal binding region, supporting substrate promiscuity and establishing ...

Metabolic mRNA insufficiency of single cells: Implications for drug targeting and resistance

open access: yesThe FEBS Journal, EarlyView.
Because none of the single‐cell mRNA profiles of growing cell populations encoded any pathway towards cell growth, we used cluster‐averaged transcriptomes to estimate protein‐constrained Vmax's and identify (combinations of) subpopulation‐specific targets to overcome drug resistance. (Graphical Abstract was created in BioRender. Liu, Y. (2026). https://

Transcriptomic and proteomic signatures underlying nymphal adaptation and foam production in the forage pest Mahanarva spectabilis

open access: yesInsect Molecular Biology, EarlyView.
RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...
