This study analysed the make-up and regulation of the biosynthetic pathway for L-lysine and related L-aspartate family amino acids (AFAAs) in Vibrio natriegens DSM759 to provide a comprehensive basis for future metabolic engineering endeavours aiming at developing this strain into an amino acid overproducer.

Regulation of extracellular vesicles for protein secretion in <i>Aspergillus nidulans</i>

Regulation of extracellular vesicles for protein secretion in Aspergillus nidulans

Rebekkah E. Pope1, Patrick Ballmann2, Lisa Whitworth3 and Rolf A. Prade1,*

This study reveals that Aspergillus nidulans boosts extracellular vesicle production when ER-trafficked enzymes are induced, uncovering how fungi remodel their secretome through vesicle-mediated secretion to adapt to changing environments and biofilm formation.

Transcriptomic response to different heme sources in <i>Trypanosoma cruzi</i> epimastigotes

Transcriptomic response to different heme sources in Trypanosoma cruzi epimastigotes

Evelyn Tevere1,a, María G. Mediavilla1,a, Cecilia B. Di Capua1, Marcelo L. Merli1, Carlos Robello2,3, Luisa Berná2,4 and Julia A. Cricco

This study uncovers how the Chagas disease parasite adapts to changes in heme, an essential molecule for its survival, providing transcriptional clues to heme metabolism and identifying a previously unreported heme-binding protein in T. cruzi.

Sir2 regulates selective autophagy in stationary-phase yeast cells

Ji-In Ryua, Juhye Junga, and Jeong-Yoon Kim

This study establishes Sir2 as a previously unrecognized regulator of selective autophagy during the stationary phase and highlight how cells dynamically control organelle degradation.

Luminal acetylation of microtubules is not essential for <i>Plasmodium berghei</i> and <i>Toxoplasma gondii</i> survival

Luminal acetylation of microtubules is not essential for Plasmodium berghei and Toxoplasma gondii survival

Thrishla Kumar1,a, Katharina Röver2,a, Johannes F. Stortz3,a, Annika M. Binder2,a, Benjamin Spreng2, Madlen Konert2, Markus Meissner1, Friedrich Frischknecht2,4 and Elena Jimenez-Ruiz1,*

Acetylation of α-tubulin at lysine 40 is not essential for cytoskeletal stability in Plasmodium berghei or Toxoplasma gondii, suggesting redundancy and plasticity in microtubule regulation in these parasites.

The dual-site agonist for human M2 muscarinic receptors Iper-8-naphtalimide induces mitochondrial dysfunction in <i>Saccharomyces cerevisiae</i>

The dual-site agonist for human M2 muscarinic receptors Iper-8-naphtalimide induces mitochondrial dysfunction in Saccharomyces cerevisiae

Angela Cirigliano1,a, Antonia Amelina2,a, Elena Passarini2, Alessandra Ricelli1, Nicole Balasco1, Mattia Mori3, Bruno Botta4, Maria Egle De Stefano2,5, Claudio Papotto6, Claudia Guerriero2, Ada Maria Tata2,5 and Teresa Rinaldi2,*

S. cerevisiae is a model to study human GPCRs. N-8-Iper, active against glioblastoma via M2 receptor, causes mitochondrial damage in yeast by binding Ste2, highlighting evolutionary conservation of GPCRs.
