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

open access: yesFEBS 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.

The histone HS gene is flanked by S1 hypersensitive structures

open access: yesNucleic Acids Research, 1984
The potential of the cloned histone H5 gene to form altered DNA structures has been examined by S1 nuclease digestion of supercoiled recombinant plasmids containing up to 8.8 kbp of chicken DNa. The three main nicking sites map at the upstream and downstream sequences flanking the structural gene.

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

open access: yesFEBS 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.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Tomato transcriptome and mutant analyses suggest a role for plant stress hormones in the interaction between fruit and Botrytis cinerea. [PDF]

open access: yes, 2013
Fruit-pathogen interactions are a valuable biological system to study the role of plant development in the transition from resistance to susceptibility. In general, unripe fruit are resistant to pathogen infection but become increasingly more susceptible

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Exploring the Prevalence of Virulence Genes of Helicobacter pylori and their Association with Gastrointestinal Diseases in South Indian Tamils

open access: yesJournal of Pure and Applied Microbiology
Helicobacter pylori, a Gram-negative gastric pathogen and a class I carcinogen harbors key virulence genes such as vacA, cagA, ureC, homB and oipA that contributes to gastrointestinal diseases. The study assessed the prevalence of H. pylori infection and
