SARS‐CoV‐2 nucleocapsid protein variants have differential RNA chaperone activity

open access: yesThe FEBS Journal, Volume 293, Issue 9, Page 2579-2598, May 2026.
The SARS‐CoV‐2 nucleocapsid (N) protein is not only the specific viral RNA packaging protein, but also acts as an RNA chaperone, facilitating RNA folding. We show that it facilitates RNA annealing through its RBD–IDR2–CTD region, identifying it as a functional RNA chaperone.

Enzymatic synthesis of bioactive quinolones and (thio)coumarins by fungal type III polyketide synthases

open access: yesThe FEBS Journal, Volume 293, Issue 9, Page 2673-2691, May 2026.
Quinolones are valuable scaffolds for drug discovery but are rare in nature. Here, we show that two fungal enzymes, AthePKS and FerePKS, can generate 2‐quinolones and two additional heteroaromatic scaffolds. Using AthePKS, we designed an artificial enzymatic cascade towards an antimicrobial quinolone from a simple precursor and implemented it in E ...

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

open access: yesThe FEBS Journal, Volume 293, Issue 9, Page 2772-2793, May 2026.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...
