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

EFFECTS OF SPRINT INTERVAL TRAINING ON ATHLETES' SPEED

open access: yesRevista Brasileira de Medicina do Esporte, 2023
ABSTRACT Introduction: The sprint is a track and field event that combines strength and speed. It has a cyclical nature. Each muscle group involved in the starter completes hundreds of contractions. Maximum strength and the fastest muscle contraction are the best combinations. This is the explosive power of runners.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

open access: yesFEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.
