Mapping the Substrate Specificity Landscape of PAD2 and PAD4 Enzymes

open access: yesChemBioChem, Volume 27, Issue 11, 15 June 2026.
Protein citrullination, driven by peptidyl arginine deiminases (PAD2, PAD4), is linked to multiple diseases. Using a combinatorial peptide library and advanced mass spectrometry, we reveal distinct substrate selectivity profiles of PAD2 and PAD4. While PAD2 broadly citrullinates arginine‐containing peptides, PAD4 is highly sequence‐restricted, with ...

Activation of Glucocorticoid Receptors By Thioredoxin.

open access: yes, 1984
Rat liver cytosol contains two distinct heat-stable activities that affect the binding capacity of glucocorticoid receptors. One activity activates receptors from a non-binding to a steroid-binding form and the other stabilizes the activated receptors ...

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

open access: yesFEBS Letters, Volume 600, Issue 11, Page 1621-1637, June 2026.
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

Cars2‐Mediated Cysteine Catabolism Drives Brown Fat Development and Thermogenesis Through Persulfidating EBF2

open access: yesAdvanced Science, Volume 13, Issue 31, 4 June 2026.
We demonstrate that Cars2, a cysteine catabolic enzyme in mouse iBAT, is critical for cold tolerance and brown adipocyte differentiation. Through its CPERS activity, Cars2 produces CysSSH/H2S to induce EBF2 persulfidation, promoting its interaction with PPARγ and BRG1 to enhance thermogenic gene expression.
