Allelic variation of the AvrSr50 effector increased virulence of the Puccinia graminis f. sp. tritici on Sr50-carrying wheat lines [PDF]

Journal of Advances in Plant Protection
Wheat stem rust, caused by the biotrophic pathogen Puccinia graminis f. sp. tritici (Pgt), is an important disease worldwide. To overcome host immunity, Pgt secretes several effectors, including AvrSr35 and AvrSr50.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Production of Mevalonate from Glycerol by Escherichia coli Citrate Synthase Variants

Fermentation
Mevalonate is a biochemical precursor to a wide range of isoprenoids. Because the mevalonate pathway uses three moles of acetyl–CoA, native pathways which metabolize acetyl–CoA, including citrate synthase, strongly compete with mevalonate synthesis.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Development of a Novel Loop-Mediated Isothermal Amplification Method to Detect Guiana Extended-Spectrum (GES) β-Lactamase Genes in Pseudomonas aeruginosa

Frontiers in Microbiology, 2019
Infections caused by multidrug-resistant Pseudomonas aeruginosa in hospitalized patients are often fatal, and nosocomial infections caused by Guiana extended-spectrum (GES) β-lactamase-producing strains are of growing concern.

Push It to the Limit: Identification of Novel Amino Acid Changes on the Acetolactate Synthase Enzyme of Rice That Putatively Confer High Level of Tolerance to Different Imidazolinones

Frontiers in Bioengineering and Biotechnology, 2020
Advancements in genetically modified herbicide tolerance technology opened a new way to manage weed populations in crop fields. Since then, many important genetically modified crops that are tolerant to various herbicides have been developed and ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Novel Mutations in K13 Propeller Gene of Artemisinin-Resistant Plasmodium falciparum

Emerging Infectious Diseases, 2015
We looked for mutations in the Plasmodium falciparum K13 propeller gene of an artemisinin-resistant parasite on islands in Lake Victoria, Kenya, where transmission in 2012–2013 was high. The 4 new types of nonsynonymous, and 5 of synonymous, mutations we

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
